HEATING WITH 4-SPEED CONFIGURATIONS

WATER CONSENT

Water temperature control for opening consent only 
concerns configurations with 3-way valves and electrical 
heater. In such configurations the water temperature will be 
checked in the following cases: 

• 

Heating with heater: heater operation requires forced 
ventilation; it is therefore necessary to avoid water that 
is too cold from passing through the unit.

• 

Post ventilation due to the heater switching off: 
maintained until the end of the set time, even if the 
operation mode is changed. During post-ventilation 
water consent coincides with consent required for 
ventilation.

ELECTRICAL HEATER

SWITCHING IT ON

If it has been preventively included by the configuration 
parameter and use is enabled by the setup parameter, the 
electrical heater is used when the thermostats requires it, 
based on the room temperature:

Switching it on entails forced ventilation.

WATER CONSENT

Consent to switch on the heater depends on water 
temperature control. The following is the relative consent 
logic:

HEATING

This enabling signal will not be given if the water probe is not 
included or is disconnected.

ECONOMY

If it has been preventively included by the configuration 
parameter and use is enabled by the setup parameter, the 
Economy function will correct the setpoint by 2.5°C and 
force operation at the minimum available seed to reduce unit 
operation.

• 

Cooling:

 set + 2.5°C

• 

Heating:

 set – 2.5°C

MINIMUM TEMPERATURE CONTROL

If it has been preventively included by the configuration 
parameter and use is enabled by the setup parameter, when 
the thermostat is off, this logic avoids the room temperature 
from dropping below a settable threshold ("Minimum 
temperature control SET"), forcing the unit to heating mode 
for the required amount of time.
If the electrical heater is present, it will be used only if it was 
previously selected as a resource in the Heating mode.

SWITCHING IT ON

If this control is selected, the terminal will turn on if the room 
temperature falls below 9°C:
