KMC Controls CTC-5500 Series Two‑Pipe Room Thermostat, Single Setpoint

Two‑Pipe Room Thermostat, Single Setpoint
CTC-5500 Series

The CTC-5500 series room thermostats are designed for use in HVAC systems for the control of pneumatic valves and damper actuators. They are fully proportional, two-pipe relay thermostats which require main air at the thermostat. Offering acute accuracy, small size, and simplistic design, they are single setpoint units for either direct or reverse acting. The removable cover allows access to the adjustment screw if recalibration if required. An optional setpoint cover may be added on top to conceal the setpoint adjustment.
