The Dual Adjustable Thermostat ZR 011 (part number 01172.0-00) from STEGO features two thermostats in a single casing, allowing for independent control of heating and cooling systems. The normally closed (NC) thermostat regulates heaters by opening the contact when the temperature rises, while the normally open (NO) thermostat controls filter fans and heat exchangers by closing the contact upon temperature increase. This model has a switch temperature difference of 7 K with a tolerance of ¬±4 K, and utilizes a thermostatic bimetal sensor element. It offers a high switching capacity of AC 250 V, 10 (2) A and AC 120 V, 15 (2) A, with a maximum inrush current of 16 A for 10 seconds. The thermostat is designed for easy installation on a 35 mm DIN rail and has a compact size of 67 x 50 x 46 mm, weighing approximately 90 g. The operating temperature range is -45 to +80 ¬8C, and it is rated for a maximum humidity of 90% RH (non-condensing). The product is housed in a light grey plastic casing compliant with UL94 V-0 and has an IP20 protection rating. It is approved by VDE, UL, CSA, EAC, and CQC, making it suitable for various applications requiring reliable temperature control.
The ZR 011 houses two separate thermostats, allowing the independent control of heating and cooling or other equipment.
Thermostat NC (normally closed):
Thermostat opens at temperature rise - for regulating heaters or for switching signal devices. Comes with red temperature dial.
Thermostat NO (normally open):
Thermostat closes at temperature rise - for regulating filter fans and heat exchangers or for switching signal devices. Comes with blue temperature dial.
