Applications
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.
