RCU50.2U Room Temperature Sensor with
manual heating/cooling changeover switch.
RCU15U/RCU50U
Room Temperature Controller.
Description
The RCU15/50… Series microprocessor controlled CAV
room controllers are designed for air only, or air and water
heating and/or cooling systems. Controllers have
two-position, pulse width modulation (PWM), or
proportional response.
Features
•
0 to 10 Vdc output for heating or cooling (RCU50U and
RCU50.2U)
•
ON/OFF or PWM outputs for heating and cooling
(RCU15U)
•
Control depending on room or return air temperature
(RCU15U)
•
Automatic heating/cooling changeover (RCU15U and
RCU50U)
•
Manual heating/cooling changeover (RCU50.2U)
•
Operating modes: Normal, Energy Saving, Freeze
Protection and Standby (RCU15U and RCU50U)
•
Operating modes: Normal and OFF (RCU50.2U)
•
Active 0 to 10 Vdc input for setpoint shifting (RCU50U)
•
Operating mode changeover input for remote control
(RCU50U)
•
Adjustable minimum limitation for cooling output
(RCU50U)
• Operating voltage 24 Vac
Applications
Controlling individual room temperature in HVAC
installations that are heated or cooled.
Controlling these types of equipment:
• Valve
actuators
• Air damper actuators
