How to use

Mount the controller in a suitable panel cut-out or inside an enclosure ensuring adequate ventilation and access to wiring terminals. Connect the 230 V supply and wire the heating or cooling load to the relay output following applicable electrical standards. Attach an appropriate temperature sensor at the measurement point and set the desired temperature using the device controls. Verify operation by observing the switching behavior around the setpoint and adjust hysteresis or setpoint as required for the application.

Usage recommendations

Install the controller in a dry, dust-free environment and route wiring to avoid interference. Choose sensor placement representative of the controlled volume to minimise measurement error. For inductive loads, use an appropriate contactor or suppression device if switching exceeds the controller’s resistive rating. Regularly inspect terminals and connections for tightness and check controller calibration as part of scheduled maintenance.
