Description

Digital Thermostat W1209 – adjustable -50°C + 110ºC

W1209 thermostat. Uncomplicated integrated thermostat module with which we can control the receiver up to 2300W.

• The module has a detachable thermistor which is located in the thimble, making it waterproof, and it measures the temperature of air as well as liquids.
• The process of setting the temperature is very simple, just press the „SET” button – then the display starts flashing and with the + and – buttons you set the desired temperature value.
• The module has heating and cooling function: H/C, depending on the selected function, e.g. H, the relay will be on below the set value until it is reached + set, or no hysteresis.
• However, function C or cooling, the relay will switch on above the set temperature and work until it is reached.
• The module remembers the set value even when the power is disconnected.
