FWECSA
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:
