Setting Heating Cycle Rate. (OP:03)
In cooling, the cycle rate is fixed at 4 Cycles per
hour. To set the cycle rate in heating; while in
installer setup,
a.
Press
∆
key, the display will
show the heat cycle rate.
b. Press
∇
key to change the heat
cycle rate to 1,3,4,5,6,9 or 12
cycles per hour.
Note: The default is set at 6 cycle per hour.
Table 4 is the recommended cycle rate. The
installer should consult with the heating
equipment manufacturer for proper use.
Setting cooling algorithm. (OP:04)
The cooling algorithm can be selected as normal or
aggressive. For aggressive, the system will cool down
the room to setting point faster than normal algorithm.
However, an overshoot might be occurred in some
situations.
a. Press
∆
key to show the cooling
algorithm.
b. Press
∇
key to change algorithm.
0 = Normal algorithm (default).
1 = Aggressive algorithm.
Setting Cooling Delay Time. (OP:05)
In some applications, there is a necessity to delay the
operation of the cooling equipment for protection
purposes. While in the installer setup,
a.
Press
∆
key. The display will
show cooling delay time.
b.
Press
∇
key to select the cooling
delay time (0,3,5 minutes).
NOTE : The default setting is 3
minutes.
Temperature offset. (OP:06)
The temperature can be offset from +3 to -4
°
F to
eliminate the effect of installing location (e.g. direct
sunlight). The thermostat will indicate room
temperature by using actual reading plus (or minus )
the offset value.
a. Press
∆
key to show temperature
offset.
b. Press
∇
key to select offset
value (default = -1
°
F).
NOTE : The default setting is -1
°
F.
