ZR011 DUAL THERMOSTAT
- NO and NC in one casing
- Separate adjustable temperature
- Terminals easily accessible
- High switching capacity
- Clip fixing
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.
