Cycles Per Hour
Section D
You can set the number cycles per hour (CPH) for the
heating operation. The default setting for heating cycles
per hour is automatic.
Heating CPH:
•
• When the thermostat is connected to a tN4 System
Control, the thermostat uses the CPH setting on the
tN4 System Control for the Heating CPH.
•
• To manually set the cycles per hour when the thermostat
is not connected to a tN4 System Control, go to the
Adjust menu and select the Heat CPH item.
•
• When the thermostat is connected to a tN4 system with
only thermostats, the SYNC setting synchronizes the
operation of all the thermostats to 5 CPH.
