Regulation of the KZT Plus boiler
Switching Summer/Winter
Hold the button for 1 second (see 6 - Pic.2).
The Summer sign appears on display (see 10 - Pic.1). Boiler will make only DHW. The antifreeze
system remains active. To cancel the Summer mode, hold the button for 1 second again (see 6 - Pic.2).
Regulation of the heating water temperature
It is possible to set the temperature from the minimum of 20°C up to the maximum of 90°C by the
buttons of heating (see 3 and 4 - Pic.2).
Regulation of the DHW temperature
It is possible to set the temperature from the minimum of 10°C up to the maximum of 65°C by the
buttons of DHW (see 1 and 2 - Pic.2).
Setting of the environment temperature (with additional room thermostat)
Set the required temperature in premises by the room thermostat. If the room thermostat is not
connected, boiler will keep temperature in supply system at value that was set at the inlet into the
supply system.
Environment temperature setting ( additional time remote control)
Set the required temperature in premises by the
. Boiler will treat water in device
time remote control
adequately to the required temperature of environment. Farther in this manual you will find instructions
for operation with time remote control.
Equithermic regulation of the KZT Plus, KST Plus, KT Plus, KT small Plus boilers
After installation of external probe (additional), the external temperature measured by the external
probe is displayed on the screen of the control panel (See 5 - Pics.1 and 2).
Boiler regulation system works with the „Controlled temperature“. In this mode is temperature of the
heating device regulated according to the external climatic conditions to ensure higher comfort and
energy savings during the whole year. Moreover, after increasing of the external temperature is the
temperature at the boiler outlet decreased according to the concrete „ compensation curve“. By
regulation of the equithermic regulation of temperature, the temperature set by the buttons of heating
(See 3 and 4 - Pics.1 and 2) represents maximum temperature at the inlet into the heating device.
It is recommended to set maximum temperature to enable system operation within the full interval.
Boiler must be set by specialist during the installation. Necessary adjustment for higher comfort can be
done by user.
Compensation curve and shift of curves of the condensing boilers Plus
Press button once to display actual compensation curve (See 6 - Pic.1 KST, KT and See 10 - Pic2 KZT).
It is possible to change it per DHW buttons (See 1 and 2 - Pic.1 and 2). Adjust the required curve from 1
to 10, adequately to the characteristics. By adjusting curve to 0 is the regulation of the controlled
temperature cancelled.
Compensation curve of the Plus condensing boilers
Access to the paralel curves shifting is enabled through heating buttons (See 3 and 4 - Pics. 1 and 2).
Flickering text (OF) is displayed. It is possible to change it through DHW buttons. (See 1 and 2 - Pics. 1
and 2).
Parallel shift of the curves of the condensing boilers Plus
Repeated pressing of the button (See 6 - Pic.1 KST, KT ) and (See 10- Pic.2 KZT ) enables to exit
mode of the parallel curve regulation. If the environment temperature is lower than required
temperature, it recommended to set more abrupt curve and vice-versa. Decrease or increase for 1 unit
and check the result in the room.
