Freeze Protection
The Freeze protection feature does not allow the room temperature to drop
below predefined cut-in temperature. Depending on which configuration the
system is operating under (W/WO Heat pump), this feature forces the
system to operate in heat mode and activate the fan.
This feature takes effect when the thermostat is either ON or OFF. When the
room temperature rises above the predefined cut-out temperature, the
thermostat returns to its previous state.
When freeze protection is activated, the display alternates between “AL”
and room temperature.
Economizer
Economizer is used to reduce the energy consumed by the cooling systems, by using low external air temperatures to assist
in the chilling process. When outdoor temperatures are lower relative to indoor (room) temperatures, the system utilizes the
cool outdoor air as a free cooling source.
The outdoor temperature (Teconomizer) triggering the activation of the economizer, can be measured by the temperature
sensor connected to T1,0 terminals (technician parameter P08="05") or by setting a temperature value manually through
communication - AV#129 "TEconomizerEffective".
When getting the temperature through communication, terminals T1,0 can be used for any other functionality like External
sensor/Soft start in heat sensor/De-icing in cool/Door switch/Key tag.
Whenever there is demand for cooling and the outdoor temperature conditions allow the operation of the economizer, it
operates together with the regular cooling system and does not replace it.
Economizer starts when, and run as long as, both of the following conditions are satisfied:
1 Teconomizer temperature < Room temperature - (Cool differential band / 2)
2 Room Temperature > Setpoint temperature
Economizer stops when the following condition is satisfied:
Room Temperature < Setpoint temperature - (Cool differential band / 2)
