Min SH
Minimum supply heat
temperature setpoint
Default value = 64 °F
(18 °C)
Sets the minimum supply heat to be maintained by the
controller during occupied periods (Occupied or
Temporary Override).
50 °F to 72 °F (10 °C up to 22 °C)
(increments: 0.5° or 5°)
IMPORTANT: To be active, the Minimum Supply Air

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 be
turned on and off in the span of an hour.
Note that a higher C.P.H will represent a higher accuracy
of control at the expense of wearing down mechanical
components faster.
3 or 4 C.P.H.
