UC150 is a communicative room heating controller with one PWM output and a room sensor for control of a radiator or electrical heater. The controller is easy to operate with a turn/push button and features a legible 60 x 60 mm LCD display and a weekly time scheduler with RTC.
The controller reads actual room temperature, setpoint shift by a knob, and set operation status which is set by short push of the knob (Comfort/Standby/Off/Party/Time schedule). Each operation mode has independent heating and cooling setpoints. Measured and set values are processed in a PI algorithm, at the output of which there is a PWM controlled 24 V triac. The output works either as PWM controlled by a PI controller, or on/off (thermostat). The functionality and control parameters, i.e. P and I constants, and hysteresis, can be set with a free configuration software, or by direct writing into the Modbus registers. See also UC250 (2x DI, 2x DO).
