- A snap on lid with window
- Sealable internal setpoint adjuster
- Thermostat module with single pole change over contacts (TB has normally-closed contacts)
- Capillary Tube (that can be uncoiled according to needs, depending on the fitting method)
- Sensor cartridge screw terminals: for wire of max 1.5mm2, cable screw fitting for cable of up to ⌀ 9mm
RAK Universal Thermostats are suitable for use in:
- Heating Systems
- Boilers Systems
- Domestic Water Boilers
- Ventilation Ducts
- Industrial Baths
