Cooling with Proportional Hot Water Reheat
In this application, with limits at the thermostat, the
CTE-1004 (DA cooling and RA heating) is used in
conjunction with the REE-4006 time proportioning
relay module and the (NC) VEP-12/22/34 series hot
water valve. The REE-4006 relay is designed for time
proportioning control of electrical hot water valves.
Aer the thermostat drops below setpoint, it
energizes the relay to open the hot water valve for
heat. As the thermostat temperature decreases, the
percent on-time of the water valve increases, forcing
it open. Once the thermostat is satised the process
reverses.
To use a NO hot water valve, replace the REE-4006 in
this application with the REE-4023 Relay Module.
NOTE: The transformer must supply a minimum
of 14 VA plus the requirement for the reheat
valve (14 VA).
