Domestic Hot Water Restart Based
On Water ∆T
Heating Restarts Based On Water ∆T
Cooling Restarts Based On ∆T
If "Auto" mode (unit opeartion mode, set by press "M" button) is set, unit needs to switch between cooling and heating
automatically, either according to "ambient temperature" (parameter 3=0) or "external signal" (parameter 3=1).
If setting=
“
via. Ambient Temp.
”,
the system will automatically switch between cooling and heating functions
,
based on the outdoor ambient temperature
:
When Ambient temperature is lower than value set in parameter 4, unit
activate heating operation.When Ambient temperature is higher than value set in parameter 5, unit activate cooling
operation.
If setting="via. External Signal", an external room thermostat or central control system in the building can control the.
cooling or heating requirements by connecting it to the respective signal ports. The signals are simple 1-0 (on-off) signals

Cooling Restarts Based On ∆T
Domestic Hot Water Restart Based On ∆T:
After sanitary hot water is heated up to the set temperature, unit will stop sanitary hot water operation. It will activate
sanitary hot water operation after temperature drops "Hot Water Restart Based On Water ∆T" below set temperature.
Heating Restart Based On ∆T:
After house heating temperature is heated up to the set temperature, unit will stop heating operation. It will activate
heating operation after temperature drops "Hot Water Restart Based On ∆T" below set temperature.
Cool Restart Based On ∆T:
After house cooling temperature is cooled down to the set temperature, unit will stop cooling operation. It will activate
cooling operation after temperature increases "Hot Water Restart Based On ∆T" above set temperature.
