Cycles Per Hour Section D
You can set the number cycles per hour (CPH) for both
the heating and cooling operations. 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.
Cooling CPH:
The default setting for cooling cycles per hour is
automatic.
•
• To manually set the cycles per hour, go to the Adjust
menu and select Cool CPH.
Fan CPH:
•
• The fan cycles per hour is tied to the cooling cycles
per hour. When cooling is not used, the fan then uses
1 CPH.
Temporary Room Set Adjustment (Schedule Only) Section C3
Pressing the up or down button while viewing the Room
or Room Set temperature during scheduled operation
allows for a temporary change in temperature. When the
temporary change is in effect, the words “TMPY HOLD”
are shown on screen. By default, the temporary change lasts for 3 hours. This
duration can be changed by going to the “Temporary Zone
Hold” item in the Scene menu.
The temporary change can be cancelled before it expires
by pressing the Up and Down buttons at the same time.
