NOTES ABOUT VALVE ACTIVATION
The appliance includes a condensation drain pump as part of the standard supply. Using a thermal
contact sensor (TC), this pump always operates when the appliance is filled with cold water, thus in
the cooling phase.
The pump remains stationary when the temperature of the water entering the bank exceeds 25 °C and no
VF
condensation is formed. Connect the TC sensor to the cooling coil inlet pipe. If the valve kit accessory is used
VF
(this is obligatory if the unit is used for cooling), always place the sensor on the cooling exchanger inlet.

The valve can be controlled by means of the switch or the two thermostats supplied as accessories, depending
on the type of installation.

With use of the switch:
· The valve is activated in parallel to the fan, regardless of the speed selected and without delays between
activation of the valve and fan. In the heating mode, fan activation can depend on the water entering the
appliance reaching a minimum temperature, monitored by enabling thermostat TC-F supplied as an accessory
and which should be installed on the bank inlet pipe.
With use of the advanced basic/thermostat:
· If the appliance is to be used in the cooling mode, the ambient temperature is monitored through activation of
the valve, which thus becomes obligatory. In this case, the fan remains permanently activated.
· In the heating mode, the ambient temperature can be monitored by the valve which opens or closes, thus
maintaining the ventilation action permanently activated (thermostat controlled valve), or through activation
of the fan, with water supply to the bank permanently activated (thermostat controlled fan). In this case, fan
activation can depend on a minimum bank inlet temperature (35°C) controlled by sensor SB supplied with
electronic thermostats. This sensor should be installed (see fig.2-3).
