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 versions),
the force in the bellows system exceeds the spring force of
the valve, and the valve opens.
In 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. If the temperature relief valve is opened, the heat
exchanger fills up and dissipates excessive heat from the
heating water to the drain.
In case of installation downstream of the boiler, at the
hot-water outlet:
The temperature relief valve closes the outlet. If the tempera-
ture 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 excessive heat from the water
heater to prevent overheating.

7. Assembly

7.1. Installations Guidelines
• The valve and the sensor must be installed carefully to
avoid any damage to 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
valve
• A sufficiently dimensioned discharge line must be provided

Attention!Installation of the thermal discharge safety
valve does not replace the diaphragm relief value in the
cold water supply line to the water heater.
7.2. Assembly instructions
1. Install a thermal discharge safety valve according to the
installation diagram
• Flow direction is marked by an arrow
2. Push the heat sensor into the immersion pipe up to the
stop point and secure with a round screw to stop it being
pulled out

8. Start-up

On commissioning the heating system, the person
preparing the system must check that the thermal
discharge safety valve is functioning perfectly.
