Frost protection monitor for water systems with 10 mm hose system

The currentless Truma safety/drain valve automatically drains the boiler if there is a risk of frost (approx. 3 °C) or excess pressure via a corresponding drain.
(or simply your entire water system)

• Suitable for all pressure or submersible pumps up to 2.8 bar (max. 4.5 bar)
• at overpressure of approx. 3.5 bar, the pressure is automatically released
• Manual opening possible when emptying the water content

Technical data:

• Water pressure (operating pressure): 2.8 bar+
• Closing temperature: from approx. 7 °C (ambient temperature)
• Opening temperature: belowapprox. 3 °C (ambient temperature)
• Operating temperature: -30 °C - +80 °C
• suitable for drinking water
• Weight:200 g
• Version with connections (for flexible hoses Ø 10 mm)

Can be used as it is or as an accessory for Truma Boiler or Trumatic C:

• As a spare part for the Truma Combi
• The FrostControl is not suitable as an accessory for the boiler.

Scope of delivery:

• Frost Control
• Angle connections

The controller is mounted on the floor underneath the water system and automatic draining can take place by means of a hole through the floor. The part triggers at 2-3°, so it makes sense not to install this part right next to a heater so that the temperature for triggering is always correct. When you return from vacation, you can also use this valve to empty the system manually. I have not yet found an official way to block the part, but the rear blue trigger button could be blocked, then it is simply always closed. (But this can lead to frost damage!)
