Sensor
The collector calculates the switching points including the switching differential
from the DHW setpoint and the acquired DHW storage tank temperature.
Thermostat
The DHW temperature is controlled based on the switching state of a thermostat
connected to B3.
When using a DHW control thermostat, Reduced mode is not possible. This means
that when Reduced mode is active, DHW heating with the thermostat is locked.
The adjustment of the nominal DHW temperature setpoint must be equal to or
higher than the setpoint adjustment on the thermostat (thermostat calibrated at
switch-off point)
The flow temperature setpoint for DHW must be set to a minimum of 10 °C (with
impact on the charging time)
DHW frost protection is not guaranteed.
