E) Hysteresis Of The Boiler; F) Hysteresis Of Uhw - TECH ST-81 User Manual

II.e) Hysteresis of the boiler
This option allows setup of the set temperature hysteresis. This
value represents a difference between the temperature of the
temperature maintenance mode activation and the operation
mode restoration temperature (e.g. if the set temperature is
60°C and the hysteresis value is 2°C, the temperature
maintenance mode will be activated at 60°C, whereas the
operation mode will be restored upon drop to 58°C. The
hysteresis value may range from 2°C to 6°C.
II.f) Hysteresis of UHW
This option allows setup of the set temperature hysteresis. This
value represents a difference between the set temperature
(required boiler temperature) and the boiler temperature (e.g.
if the set temperature is 55°C and the hysteresis value is 5°C,
upon reaching the set temperature i.e. 55°C, UHW pump is
turned off and CH pump is activated. The UHW pump will be
activated upon temperature drop to 50°C).
