Cooling Output Cycles Per Hour
CPH is used to "modulate" On/Off outputs controlling equipment such as
compressors. When the Room Temperature is within the Proportional Band, the
output performs 3 or 4 CPH. A higher CPH represents a higher accuracy of control
at the expense of wearing mechanical components faster.
Note: The CPH does not limit the number of Cycles Per Hour. It is limited by the "Anti
short cycle" parameter.
Range: 3 to 4 CPH
Heating Output Cycles Per Hour
CPH is used to "modulate" On/Off outputs controlling equipment such as
compressors. When the Room Temperature is within the Proportional Band, the
output performs 3 to 8 CPH. A higher CPH represents a higher accuracy of control
at the expense of wearing mechanical components faster.
For multi-stage models, heat cph applies to W1 & W2.
Range: 3 to 8 CPH
Cooling Valve
Sets the type of valve used for cooling.
NC: Valve normally closed when no power is present
NO: Valve normally opened when no power is present
