RTC22b Room Temperature Control (0-10V, or Triac Outputs)

The RTC22b is designed to provide room temperature control for heating and/or cooling circuits. There are two versions of the RTC22b/A for analogue control of two
0 to 10V outputs whilst the RTC22b/T is used for 24V AC outputs. The RTC/power supply can be 24V AC or DC supply for the RTC22b/A (0-10V version) but only 24Vac for the RTC22b/T.

The required temperature (setpoint) is adjusted using the +/- buttons on the front of the controller. The display normally shows the measured temperature and when the buttons are pressed the setpoint is displayed for a time period to allow adjustment to take place. Alternatively the display can be set up to show the setpoint value only.

All control options and settings are programmed using the controller display.
