NOTICE
Make sure to select and install the safety thermostat
according to the applicable legislation.
In any case, to prevent unnecessary tripping of the safety
thermostat, we recommend the following:
▪ The safety thermostat is automatically resettable.
▪ The safety thermostat has a maximum temperature
variation rate of 2°C/min.
▪ There is a minimum distance of 2m between the safety
thermostat and the motorized 3‑way valve delivered
with the domestic hot water tank.
INFORMATION
ALWAYS configure the safety thermostat after it is
installed. Without configuration, the unit will ignore the
safety thermostat contact.
INFORMATION
The preferential kWh rate power supply contact is
connected to the same terminals (X5M/9+10) as the safety
thermostat. Thus, the system can have EITHER
preferential kWh rate power supply OR a safety
thermostat.
6.3.11 To connect a Smart Grid
This topic describes 2 possible ways to connect the outdoor unit to a
Smart Grid:
▪ In case of low voltage Smart Grid contacts
▪ In case of high voltage Smart Grid contacts
This requires the installation of the Smart Grid relay kit
(EKRELSG).
In case of low voltage Smart Grid contacts
Wires (Smart Grid pulse meter): 0.5mm²
Wires (low voltage Smart Grid contacts): 0.5mm²
[9.8.4]=3 (Benefit kWh power supply = Smart grid)
[9.8.5] Smart grid operation mode
[9.8.6] Allow electrical heaters
[9.8.7] Enable room buffering
[9.8.8] Limit setting kw
The wiring of the Smart Grid in case of low voltage contacts is as
