Operation
Heating Mode
In heating mode once the slab
temperature reaches the selected
setpoint temperature the relay
will be de-energized. As the slab
temperature decreases below the
selected differential the relay will
energize.
Example: Slab setpoint is set to
85 °F differential is set to 5, once
the slab temperature is below
80 °F the relay will be energized.
Cooling Mode
In cooling mode, the differential
is above the setpoint. So as the
temperature rises higher than the
selected setpoint plus the
differential the relay is energized.
Example: Slab temperature is
set to 66 °F with a differential
of 2. When the slab temperature
reaches 68 °F the relay will be
energized.
