Maximum/minimum water temperature setting for space heating protection by Installer mode
• Heating circuit minimum/maximum temperature limits selection by installer: The installer will limit the space heating
temperature set-point in order to prevent excessively high or low temperatures.

•
Very useful when water calculation type selected is by gradient
• Temperature limits have priority against all other temperature set point modifications, and minimum/maximum
water temperature is limited by air to water heat pump’s working range.
Room thermostat units
There are available two types of room thermostat units:
•
ON/OFF room thermostat unit (accessory): When the room temperature setting is higher than the room actual tempe-
rature, it is provided a thermo-ON signal to the system. Once reached the room temperature setting, it will be provi-
ded a thermo-OFF signal to the system.
• Intelligent room thermostat unit (accessory) with extension room thermostat (accessory) for the second circuit: Based
on Outside Temperature Compensation (OTC). Water outlet target temperature is automatically recalculated taking
into account the outdoor ambient temperature and the difference between the room setting temperature and the room
actual temperature.
