CSP-5001/5002 VAV Flow Controller-Actuators 18 Applications Guide, Rev. B
Cooling with Hot Water Reheat
This application uses a CTE-5104 thermostat with
a VEP-43/VEB-46 series 3-way hot water valve to
control temperature in the conditioned space. The
valve shown below uses the (discontinued) MEP-
5062 or (fail-safe) MEP-5372 actuator for reheat
control.
With 0 VDC from the thermostat, the mixing valve
bypasses water from the supply to the return. As the
thermostat voltage increases, water begins owing
into the coil to allow heated air into the space. At 2°
below setpoint the full ow is sent through the coil.
NOTE: Jumper “T2” to “R2” for automatic
auxiliary ow for heating.
