Description
System Type
Twopipeclg – 2 pipes cooling only.
Twopipeclgelectheat – 2 pipes cooling only with electric heater.
Twopipehtg – 2 pipes heating only.
Twopipehtgelectheatt – 2 pipes heating only with electric heater.
Twopipechgover – 2 pipes change-over.
Twopipechgoverelectheat – 2 pipes change-over with electric heater.
Fourpipe – 4 pipes heating and cooling.
Fourpipeelectheat – 4 pipes heating and cooling with electric heater.
Twopipe6wayvalve – 2 pipes with a 6 way valve.
Heatpumpunit – Heat pump unit.
Other – Other system type
Change Over Delay
Defines the minimum time during which heating must be OFF before cooling can be
turned ON as well as the minimum time during which cooling must be OFF before
heating turns ON. This parameter prevents the system from continuously oscillating
between heating and cooling modes.
Setpoint Offset Range
Input the range for the setpont offset.
