REE-5002 | Relay: Fan Box, 0-10VDC Input

The KMC REE-5002 triac relay module is designed primarily for use with VAV fan-powered induction boxes. When used with a direct-acting CTE-5202 or CTE-510x room thermostat, the unit mounted fan and two stages of reheat can be controlled.

Each output circuit is capable of handling contactors of up to 10 VA @ 24 VAC. The “FAN” output circuit may be adjusted to start the unit fan at an air flow setting of 0 to 3,000 fpm. The two reheat circuits are factory-set to sequentially actuate after the fan starts if the room temperature continues to fall.

Using the REE-5002 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 actuating reheat coils.
