Volume of sanitary water circuit, primary DHW circuit (from 3-wa
y valve to confluent point with heating circuit), piping to expa
nsion vessel, and expansion vessel are not included in this val
ue.
*2
The environment must be frost-free.
*3 Cooling mode is not available in low outdoor temperature. If you use our system in cooling mode at the low ambient temperature (10°C or below), there are some risks of plate heat exchanger breaking by frozen water
.
*4 For the model without both booster heater and immersion heater
, the maximum allowable hot water temperature is [Maximum outlet water of outdoor unit −3°C]
For the maximum outlet water of outdoor unit, refer to outdoor unit data book.
*5
Tested under BS7206 conditions.
*6 Do not fit immersion heaters without thermal cut-out.
