Relay: Fan Box with Wet Reheat, DA for NC Valves, 0-10VDC Input
The KMC REE-5017 relay module is designed primarily for use with VAV fan powered induction boxes requiring proportional control of electric hot water valves in HVAC systems. The “FAN” output circuit is capable of handling contactors up to 10 VA @ 24 VAC. This circuit may be adjusted to start the unit fan on a requirement for heat prior to the valve opening, or when the valve begins to open. The “VALVE” output circuit is time proportional providing 24 VAC output to a VEP series valve. This provides complete modulation of the valve over the proportional band of the CTE-5100 series thermostat’s heating setpoint. The REE-5017 allows full adjustment of the unit fan starting point so that optimum use can be made of the warm air in the return air plenum before opening the hot water valve.
