Thermostats & Hygrostats

The RCU61U Room Temperature Controllers are designed

speciﬁcally for Constant Air Volume and Variable Air

Volume Systems.

Controlling individual room temperature in HVAC installa-

tions that are heated or cooled, the RCU61 Temperature

Controllers are suited for use with VAV systems with auxil-

iary heating with VAV compact controllers, valve actuators,

and air damper actuators.
