6.5. - Cooling
This is used to cool down e.g. storages to a setpoint temperature by radiating heat.
Settings range: S1-S8, VFS1-2, active Storage / Default setting: None
6.5.1. - Co T set
Target temperature at thermostat sensor 1. Cooling is on above this temperature till Co T set + hysteresis is reached.
Settings range: 0-99°C / Default setting: 50°C
6.5.2. - Co hysteresis
If the temperature at th drops below Co T set + hysteresis, the relay is switched off.
Settings range: -50 bis -1 / Default setting: -10
6.5.3. - Cooling (sensor)
Reference sensor of the cooling function.
Settings range: (Storage sensor) / Default setting: First storage
6.5.4. - Periods
Cooling activity times
Set the desired periods of time when the cooling should be active. 3 periods can be set per day, settings can also be
copied to other days. Outside the set times the cooling function is switched off.
Setting range: from 00:00 to 23:59 /default setting: 06:00 to 22:00

6.6. - Return
fl
ow increase
This function is used to raise the temperature of e.g. the return
fl
ow by the storage.
Settings range: On, Off
6.6.1. - RF Tmax
Maximum temperature at the storage sensor. If this temperature is exceeded, the relay is switched off.
Settings range: 0-99°C / Default setting: 70°C
6.6.2. -
∆
T return
fl
ow
Switch-on temperature difference:
When this difference is exceeded between return
fl
ow sensor and storage sensor, the relay is switched on.
Settings range: 5-20 K / Default setting: 8 K
Switch-off temperature difference:
When this difference is exceeded between return
fl
ow sensor and storage sensor, the relay is switched off.
Settings range: 2-19 K (limited by
∆
T Storage RF On) / Default setting: 4 K
6.6.3. - Return
fl
ow (sensor)
Determines the sensor for return
fl
ow increase.
Settings range: S1-S8, VFS1-2, active Storage / Default setting: none
6.6.4. - Storage (sensor)
Determines the storage sensor
Settings range: S1-S8, VFS1-2, active Storage / Default setting: none
