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.
