Relay: Fan Box, 0-6VDC Input
The KMC REE-4002 relay module is designed primarily for use with VAV fan powered induction boxes. When used in conjunction with a direct acting CTE series 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-4002 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.
