Setting the RT-820M thermal relay
Hello! How to set the threshold parameters of the given thermal relay (with LCD display and 4 buttons). From -8 to +3 degrees. I set it by setting the shutter temperature off temperature of 30 degrees by cooling and turning on 26 gr. (gestyresis 4gr.). And here are the complex parameters. Thank.

To set the thermal relay, press the SET button, then select with the arrows H - this is the heating mode, press SET again. After that, select the required temperature value (+3) with the arrows and confirm by pressing the SET button. Next, set the hysteresis value - parameter HYS. Select this item with the SET button, then select the value with the arrows - you must select 11 degrees. The temperature will be adjustable from -8 to +3 degrees (11 degrees difference). These are the settings for heating mode. If you need to configure the relay in cooling mode, then at the beginning you need to select mode C - cooling mode.
