Summer
compensation
Po
Outdoor temperature °C -10,0 25,0 50,0
Outdoor temperature to start summer setpoint compensation. The goal is to increase
the summer setpoint while the outdoor temperature rises.
Differential °C -30,0 10,0 30,0 Temperature band to calculate the compensation value
Max. compensation °C 0 5,0 15,0 Maximum summer setpoint compensation
Winter
compensation
Pp
Outdoor temperature °C -10,0 10,0 50,0
Outdoor temperature to end winter setpoint compensation. The goal is to decrease
the winter setpoint while the outdoor temperature drops.
Differential °C -30,0 10,0 30,0 Temperature band to calculate the compensation value
Max. compensation °C 0 3,0 15,0 Maximum winter setpoint compensation
Automatic
changeover
Pq
Enable N/Y Y See the Automatic changeover part.
Differential °C 0 3,0 6,0
Minimum difference between the room temperature and the winter setpoint to
change to summer mode and between the room temperature and the summer
setpoint to change in winter mode, to avoid constant switching between the modes.
Summer room
temp. threshold
Pr
High °C -10,0 32,0 50,0 High and low room temperature limits in summer mode to generate a room
Low °C -10,0 14,0 50,0 temperature alarm.
Winter room
temp. threshold
Ps
High °C -10,0 28,0 50,0 High and low room temperature limits in winter mode to generate a room
Low °C -10,0 14,0 50,0 temperature alarm.
Room high/low temp. Pt Alarm delay min 0 30 600
Time during which the room temperature must stay above the high limit or below
the low limit to generate a room temperature alarm.
Electrical heaters Pu
Offset °C -20,0 -4,0 20,0 Difference compared to the winter setpoint to have both electrical heaters ON.
Differential °C 0 2,0 10,0 Temperature band to regulate the electrical heaters stages ON/OFF.
Hot water coil valve Pv
Enabling N/Y N See the hot water coil part (option, when available).
Offset °C -20,0 -4,0 20,0
Difference compared to the winter setpoint to have the proportional valve fully
open.
Differential °C 0 2,0 10,0 Temperature band to regulate the proportional valve opening.
Gas burner Pw
Enabling N/Y Y Enables the gas burner operation (option).
Offset °C -20,0 -4,0 20,0 Difference compared to the winter setpoint to run the burner at full capacity.
Differential °C 0 2,0 10,0 Temperature band to regulate the proportional burner capacity.
