Optional PCBs • KRPs and DTA boards are essentially interface boards that allow 2 way communication with an external source. • Each PCB can have numerous settings and function differently depending on the signal provided to them. • Not all KRPs and DTAs are compatible with every Fan coil unit due to how they connect. 3

Splits FVX, FVK, FLX, FLK, FDX, FDK, FTXS units. • KRP 413 A 1 S – Not for use with G series wall mounts!! – This board gives the ability to switch the units on & off remotely (from BMS or timeclock) BMS stands for Building Management System. This KRP is also capable of providing a fault run signal and has the ability to change the units operation. • 1 Per Fan Coil • Use KRP 928 A 2 S for G Series Wall mounts. • KRP 928 B 2 S – This board gives split units the ability to be linked to a Daikin centralised controller (I Controller etc …) via the F 1 F 2 communications loop. This board is also used for the G Series Wallmounts to provide the ability to switch the units on & off remotely • 1 Per Fan Coil 4

KRP 413 A 1 S Full installation manual • This KRP is for use with Daikin Split units (excluding G Series Wallmounts!) • This boards main function is to switch the units on & off remotely but can be used to provide a fault signal and although rarely used can also change fan speed and operation mode. • The KRP 413 A 1 S is designed to plug directly into the indoor PCB board in the S 21 Connector and then be mounted on the wall in the fixing box that is included. 5

KRP 413 A 1 S - Switches • As with most KRPs there are numerous settings on the PCB which change the functionally of how it operates. • There are 2 dip switches on the PCB SW 1 -1 & SW 1 -2. SW 1 -1 determines if the FCU remote manually overides the KRP on off signal. SW 1 -2 determines if the unit will auto restart. SW 1 -1 Selecting operation mode Off On SW 1 -2 Selecting On/Off when power is restored after power failure Off On All remote control buttons available Limited remote control buttons available. Allways Off if operation was in off mode before power failure, On if operation mode was on before power failure 6

KRP 413 A 1 S – On/Off signal The On Off signal is provided to the KRP using the S 1&S 2 contact on the left hand side of the board using either a Pulsed or Constant Contact volt free signal. Generally speaking in the UK a constant volt free contact is provided. A Volt free signal is a very low (usually milliamp) power signal that just has enough energy to close a relay Link 7

KRP 413 A 1 S – Fault & Run Signal • This KRP is also capable of providing a fault run signal although doing so is not always possible as you need to provide the board with a external 12 v signal. Daikin UK used to be able to supply a board called the UK. KRP 413/IF that took a 12 v supply from the indoor unit PCB but unfortunately this has been discontinued.

The remote controller is now purely available for temperature adjustment and air flow direction, no other functions are available 13

KRP 928 B 2 S Full installation manual • This board gives split units the ability to be linked to a Daikin centralised controller (I Controller etc …) via the F 1 F 2 communications loop. Ø 1 Per Fan Coil • This board can also be used in place of the KRP 413 A 1 S and must be used with G Series Wall mounts toy to switch the units on & off remotely (from BMS or timeclock) Ø 1 Per Fan Coil 14

KRP 928 B 2 S To connect the indoor units to a DIII net (F 1/F 2 communication, e. g. Centralised or ITouch Controller) S 1 Terminals are used to turn the unit on and off via a volt free signal Connection for connector harness (S 6) to room air conditioner (S 21) Group/Address numbers are set by the dip switches SW 1 SW 2 S 8 Terminals to supply a DC 12 V required to enable terminals S 5 Terminals are to provide a fault run signal in exactly the same way as the KRP 413 A 1 s SW 3 Switches; 1 – Japan / Europe 2 – Constant /pulsed input 3 – Forced stop settings switch 15

KRP 928 B 2 S – SW 3 Switches SW 3 -3 ON For use when connecting to overseas models. Auto mode can be selected from central control equipment. When auto mode is selected using the local remote controller, auto cooling or auto heating will be displayed on the central remote controller SW 3 -3 OFF For use when connecting to Japanese models. Auto mode cannot be selected from central control equipment. When auto mode is selected using the local remote controller, auto cooling or auto heating will be displayed on the central remote controller. At this time the temperature display is fixed at 25°c SW 3 -2 On – Pulsed input SW 3 -2 Off – Constant Contact SW 3 -1 - Forced stop settings switch S 1 operating mode SW 3 -1 SW 3 -2 What Happens Setting Pulsed contact input Control mode OFF The operating status of the air conditioner is reversed by an instantaneous input of 100 msec or Last command priority more.

Close to open: no change in operating status. are prohibited. OFF Constant contact input Forced stop or remote controller permission input ON 16

KRP 928 B 2 S – Address setting, SW 1&2 Switches When linking a split unit to a centralised system an address will need to be entered for that unit so the control system can recognise it. This is done using the SW 1&2 switches setting the group number and unit number There are 8 possible groups with 16 items per group therefore 128 different address can be set 17

Sky Air Units For FHQ, FFQ, FCQH, FUQ, FBQ, FDQ, FVQ units • KRP 4 A 53 – The main function of this board is to switch the units on & off remotely via a volt free signal (from BMS or timeclock) and give a fault or run signal, it also ha s some other functions that we will look at in further detail • • 1 Per BRC 1 D Controller KRP 4 A 53 -1 – As above but also lets a BMS tell the unit(s) which setpoint temperature to use via a 0 -10 v DC signal – We do not sell this anymore as temperature setting can be more easily achieved using the new RTD boards. • KRP 1 B 57 – FHQ, FFQ, FBQ, FCQH, FDQ, FVQ units only – This Board gives a signal to a third party that indicates the fan is running on the indoor unit. This board is usually used when an additional fan is putting fresh air either into the same room or directly into the fan coil. • DTA 112 B 51 – FAQ 100 B, FHQ, FFQ, FUQ, FBQ, FDQ, FVQ units only (FAQ 71, FCQ & FCQH units do not need – this board as they already have F 1 F 2 connections) This board gives Sky Air units the ability to be linked to a Daikin centralised controller (I Controller etc …) via the F 1 F 2 communications loop • 1 Per BRC 1 D Controller 18

KRP 4 A 53 Full installation manual This commonly used adapter board is the most flexible and adaptable in the range. It can be used for: • • • Time clock control Fire shut down Remote temperature set point control. Run and fault indication. Disabling on, off and temperature buttons on remote controllers. • Using the remote controller P 1/P 2 wiring it can be connected to a maximum 16 fan coils all connected to the same remote controller. • The KRP is externally mounted in all current units apart from the FDQ and FXMQ FCUs and can no longer be mounted internal in the FBQ-C and FXSQ-P ducted units. A separate fixing box (UK. FB 2) is required 19

Run and trip signals will be available from terminals W 1 -W 2 & W 3 -W 4 Computer rooms etc Set: RS 1 to 1 SS 1 to Non Volt SS 2 to Impossible When terminals B 1 to BC are shorted the fan coils will run, it will be impossible to turn the fan coils off from the remote controller or adjust the set point temperature. When terminals B 1 to BC are opened the fan coils will stop and you will not be able to start the fan coils from the remote controller. 22

KRP 4 A 53 – RS Switch Settings RS 1 01 2 3 4 Offices etc Set: RS 1 to 2 SS 1 to Non Volt When terminals B 1 to BC are shorted the fan coils will run, it will be possible to turn the fan coils off and back on from the remote controller. When terminals B 1 to BC are opened the fan coils will stop and you will not be able to start the fan coils from the remote controller. Meeting rooms etc Set: RS 1 to 4 SS 1 to Non Volt When terminals B 1 to BC are shorted the fan coils will not run, it will be possible to turn the fan coils on and back off from the remote controller. When terminals B 1 to BC are opened the fan coils will stop and you will not be able to start the fan coils from the remote controller. 23

KRP 4 A 53 – RS Switch Settings RS 1 01 2 3 4 Pulsed time clocking from BMS Set: RS 1 to B SS 1 to Non Volt When terminals B 1 to BC are shorted for 300 m/s the fan coils will run, it will be possible to turn the fan coils off and back on from the remote controller. When terminals B 2 to BC are shorted for 300 m/s the fan coils will stop, it will be possible to turn the fan coils off and back on from the remote controller. Fire shut down terminals B 2 and BC When Rs 1 is set to 1, 2, or 4 When these terminals are shorted the fan coils all stop it will not be possible to restart the fan coils until the connection is broken. A start signal will then need to be sent to the KRP from the time clock or from the remote controllers. 24

KRP 4 A 53 A+ A- Terminals • Temperature setting via the KRP is possible (as per below) but generally speaking quite difficult to do as a variable resistance (Ohms) signal needs to be sent to the A+A- terminals. Daikin used to offer the KRP 4 A 53 -1 to change the temperature via a 0 -10 v signal this has been withdrawn and an RTD board should now be recommended for temperature setting. SS 2 Use the S 22 switch to determine if temperature setting is also available using the remote control (possible/impossible) 25

DTA 104 A 51 Full installation manual • The DTA 104 board has two possible functions, both are directly related. Reducing sound - Low noise control • The DTA 104 reduces the operational sound output from a VRV Condenser by limiting the fan and compressor speeds. This setting is usually used at nightime to limit possible sound nuisances. By using this setting you will also limit the capacity of the outdoor unit so caution should be used when applying this accessory. The only published figures for the reduction in sound relate to the VRV-S units, which at the highest setting will reduce the sound output by between 10 -12 d. BA (VRV-S Noise reduction figures) Demand Control • This setting limits the power used by the outdoor unit, it also has the effect of limiting the capacity of the condenser so again caution should be used when using this board, and is usually used in low demand periods (i. e. night time) There are three settings achievable with this adaptor • • • Whether you require demand control or low noise control you will need an external connection from another controlling source (BMS, timeclock etc) in order to activate the features of the adaptor via a volt free contact. The adaptor will also require an address setting so the condenser recognises it is installed and connection to the F 1 F 2 wiring loop. This board will also allow you to control Heat/Cool Changeover. The board is connected to an indoor unit. 36
