Frost pr
Frost protection enabled
Default value = Off
On heat pump models the system
mode will be forced to EMERGENCY
mode if frost protection is activated
Off: no room frost protection
On: room frost protection enabled in all system
mode at: 42 °F ( 5.6 °C )
Frost protection is enabled even in system Off
mode
Off or On
Heat max Maximum heating setpoint limit
Default value = 90 °F ( 32 °C ) Maximum occupied & unoccupied heating setpoint
adjustment. Heating setpoint range is:
40 to 90 °F ( 4.5 to 32.0 °C )
Cool min Minimum cooling setpoint limit
Default value = 54 °F ( 12 °C ) Minimum occupied & unoccupied cooling setpoint
adjustment. Cooling setpoint range is:
54 to 100 °F ( 12.0 to 37.5 °C )
Anticycle
Minimum on/off operation time for
stages
Default value = 2 minutes
Anti-short cycling can be set to 0
minutes for equipment that posses
their own anti cycling timer. Do not use
that value unless the equipment is
equipped with such internal timer.
Failure to do so can damage the
equipment. Minimum On/Off operation time of cooling &
heating stages.
IMPORTANT, anti-short cycling can be set to 0
minutes for equipment that posses their own anti
cycling timer. Do not use this value unless the
equipment is equipped with such internal timer.
Failure to do so can damage the equipment.
0, 1, 2, 3, 4 & 5 minutes
Heat cph Heating stages cycles per hour
Default value = 4 C.P.H.
Will set the maximum number of heating stage
cycles per hour under normal control operation. It
represents the maximum number of cycles that
the equipment will turn ON and OFF in one hour.
Note that a higher C.P.H will represent a higher
accuracy of control at the expense of wearing
mechanical components faster.
3, 4, 5, 6,7 & 8 C.P.H.
Cool cph Cooling stages cycles per hour
Default value = 4 C.P.H.
Will set the maximum number of cooling stage
cycles per hour under normal control operation. It
represents the maximum number of cycles that
the equipment will turned on and off in one hour.
Note that a higher C.P.H will represent a higher
accuracy of control at the expense of wearing
mechanical components faster.
3 or 4 C.P.H.
Deadband
Minimum deadband
Default value = 2.0 °F ( 1.1 °C ) Minimum deadband value between the heating
and cooling setpoints. If modified, it will be applied
only when any of the setpoints are modified.
2, 3 or 4 °F ( 1.0 to 2.0 °C )
Fan cont
Fan control
Default value = On Fan control in heating mode.
When selecting On; the thermostat in all cases
will always control the fan (terminal G).
Valid for On or Auto fan mode
When selecting Off; the fan ( terminal G ), when
heating stages ( terminals W1 & W2 ) are
solicited, will not be energized. The fan in this
case will be controlled by the equipment fan limit
control.
Valid only for Auto fan mode. On fan mode will
leave the fan always on.
