Safety Guidelines; Description Of Function; Application; Technical Data - Honeywell TS131 Einbauanleitung

1. Safety Guidelines

1. Follow the installation instructions.
2. Use the appliance
• according to its intended use
• in good condition
• with due regard to safety and risk of danger.
3. Note that the appliance is exclusively for use in the appli-
cations detailed in these installation instructions. Any
other use will not be considered to comply with require-
ments and would invalidate the warranty.
4. Please take note that any assembly, commissioning,
servicing and adjustment work may only be carried out by
authorized persons.
5. Immediately rectify any malfunctions which may influence
safety.

2. Description of function

The temperature relief valve is controlled by the supply
temperature of the heat exchanger. It consists of a spring-
loaded valve and a temperature sensor, which is acting on a
bellows system. When the supply temperature in the boiler
reaches the specified opening temperature (see Options), the
force in the bellows system exceeds the spring force of the
valve, and the valve opens.
In the case of installation upstream of the boiler, in the
cold-water supply of the boiler's integrated heat
exchanger:
The temperature relief valve closes the supply to the heat
exchanger. The heat exchanger itself remains dry in normal
operation. When the temperature relief valve is opened, the
heat exchanger fills up and dissipates excess heat from the
heating water to the drain.
In the case of installation downstream of the boiler, at the
hot-water outlet:
The temperature relief valve closes the outlet. When the
temperature relief valve opens, the heated city water is
drained from the heater and replaced with cold water from the
supply. This water can now absorb the excess heat from the
water heater to prevent overheating.

7. Assembly

7.1. Installation instructions

• The valve and the sensor must be installed carefully to
avoid damaging the capillary tube
• The opening on the blow-out line must be clear and easy
to monitor
• Ensure no persons are in danger when blowing off the
fitting
• A sufficiently dimensioned discharge line must be provided
