Relay: Reheat, 0-10VDC Input
These triac relay modules are designed primarily for use with VAV terminal units in HVAC systems. When used in conjunction with reverse acting outputs of the CTE-5100 series room thermostats, up to three stages of heating or cooling may be controlled.
The REE-5001 is most typically used with CTE-5104 thermostats, but it can also be used with the RA outputs of the CTE-5102 and CTE-5103.
The REE-5501 (with isolated outputs) is most typically used with BAC-5841-16 and BAC-5842-16 VAV Advanced Application Controllers to control a fan and two stages of heating or cooling (see the documents for those controllers for more information).
Each output circuit is capable of handling contactors of up to 10 VA @ 24 VAC. The three circuits are calibrated to actuate at equally spaced intervals across the thermostat’s proportional band.
By using the REE-5001/5501, heating or cooling requirements may be actuated in three separate steps, providing precise temperature control.
