03. PV / Smart Grid Connection (only BRP 069 A 61) 15

3. PV / Smart Grid Connection This function is available only when; - The unit software is TO 7 or higher - The RC software version is V 01. 17 or higher - “Full Version(BRP 069 A 61)” LAN Adapter is equipped - PV inverter or energy management system has digital output 3 -1. Functions PV / Smart Grid Connection function maximizes the self-consumption of power generated by PV within thermal buffer. (e. g. DHW tank, space heating / cooling set temperature) Pulse Signal (optional) Digital Signals Control PV Inverter / HEMS LAN Adapter Energy injection Self-consumption Power Grid 16 Pulse electrical meter (optional) P 1 P 2 HP

3. PV / Smart Grid Connection 3 -2. Operation modes LAN Adapter chooses the best operation mode depending on the situation of PV power generation and energy injection to the grid. Target: maximum self-consumption of power PV generates and minimum power injection to the grid 1. “Free running” mode There is no effect of the Smart Grid Control (=normal operation) A unit operates according to its own settings and schedule. 2. “Forced OFF” mode The operation of outdoor unit and electrical heater is deactivated to reduce power consumption in case of high energy tariff. 3. “Recommended ON” mode A Unit starts DHW, space heating or cooling to make use of PV energy. The power consumption by the unit has fix value or auto-adaptive limitation. 4. “Forced ON” mode A Unit starts DHW, space heating or cooling to make MAXIMUM use of PV energy. The power consumption by the unit has no limitation. 17

Pulse Signal (optional) Digital Signals (SG 0=1, SG 1=0) PV Inverter / HEMS LAN Adapter Energy injection Self-consumption Power Grid Operate with power limitation P 1 P 2 HP Pulse electrical meter (optional) Fix Value Power Limitation - Power limitation is set beforehand on the Web Interface by installers. - If consumption exceeds the limitation => Compressor output reduction and/or force electrical heater OFF Auto-adaptive Power Limitation (recommended) - Power limitation is automatically set based on measured power injection to the grid, and compressor output and/or electrical heaters are adjusted. The limitation is set to maximize the usage of PV and minimize power injection to the grid. 20
