RCC20U
• Outputs for on/off valve actuator and
electrical heater.
• Output for three-speed fan.
• Dual set point temperature scale.
The RCC... Room Temperature Controllers are room
temperature controllers for two-pipe fan coil units.
The RCC... Series of Room Temperature Controllers are
typically used for:
• Controlling Normally Open (NO) 120 Vac, two-position
valves. (RCC10U/20U)
• Controlling room temperature in individual rooms that
are heated or cooled with two-pipe fan coil units.
• Opening or closing a 0 to 10V Normally Closed valve.
(RCC50.1U)
• Switching an electrical heater (RCC20U).
• Operating a 3-speed fan.
The RCC... Series is suitable for systems with:
• Automatic Heating/Cooling changeover.
• Heating only/Cooling only or Heating and Cooling
applications.
RCC50.1U Room Temperature
Controller.
• Control depending on the room or return air
temperature (remote sensing).
• Automatic Heating/Cooling changeover.
• Operating modes: Normal, Energy Saving, Frost
Protection and Off.
• Operating mode changeover input for remote control.
• Selectable control parameters.
RCC50.1
• Modulating P+I control
• Output for 0 to 10 Vdc valve actuator
• Outputs for three-speed fan
• Dual set point temperature scale
• Automatic heating/cooling changeover
• Operating modes: Normal, Energy Saving and Off
• Operating mode changeover input for remote control
• Moisture damage protection function
