button can be pressed only after the boiler
water temperature drops.
Resetting the STB safety temperature limiter: 1 -
protection nut, 2 - reset button.
Dangerous voltage exists at
terminals 1-2.
12.16 Thermal protection
The controller equipped with additional
thermal protection (APT), type DZT-1. It cuts
off the fan and feeder power supply. Sensor
of the additional thermal protection, which
operates on low safe voltage, should be
placed in the thermometric pipe of the water
jacket. You should provide good thermal
contact of the DZT-1 sensor, and secure it
against coming loose from the measured
surface. If the boiler temperature exceeds
the DZT-1 sensor activation temperature
(85°C or 90°C±5 depending on the DZT-10
type), the fan and feeder power supply is cut
off. The fan and feeder power supply will be
automatically restored after the boiler
temperature drops several degrees Celsius.
The thermal protection cannot
be used instead of the
mandatory STB safety
temperature limiter.
