7. Outdoor compensated room temperature control
The room temperature can be compensated when the outdoor temperature increases. One can, for
instance, imagine accepting a slightly higher room temperature if it is warm outside or, conversely,
a slightly lower temperature if it is chilly. This function is included to conserve energy.
8. Outdoor compensated extract air control
The extract air temperature can be compensated when the outdoor temperature increases. One can,
for instance, imagine accepting a slightly higher extract air temperature if it is warm outside or,
conversely, a slightly lower extract air temperature if it is chilly. This function is included to
conserve energy.

5.1.2 Heater types
5.1.2.1 Water heating
Control
When the unit is in running mode the heating valve is controlled by the analogue output ”Y1
Heating” or by two digital outputs “Heating 3-pos. actuator, increase” and “Heating, 3-pos. actuator,
decrease”.
Frost protection
The heater return water temperature is measured using the analogue input ”Frost prot.temp”. Low
temperatures will generate an internal, proportional signal that is used to force the heating valve
open thereby preventing freeze-up of the heater.
