Navigation: SELECTION
Select your language from the language menu:
EN; DE; NL; DA; FR; IT; SV; NO; FI; RU; CZ; PL; SK; LT
next ( -> )
The unit is automatically executing a connection check of the sensors 1 and 2. If there
is no sensor connected, the unit will stop the Quickstart process. In this case, power off,
connect a sensor and power on again.
Note: 1 Sensor needs to be connected at least.

Select a country in this menu:
DE; AT; CH; GB; FR; IT; PL; CZ; DK; SE; BE; RU; NO; LT; SK; NL; FI; IE
back ( <- ) or next ( -> )
Use the +/- button to select the day, month, and year.
back ( <- ) or next ( -> )
Use the +/- button to set the hour and minute.
back ( <- ) or next ( -> )
Select the installed pipe freeze protection heating cable:
10XL2-ZH / 15XL2-ZH / 26XL2-ZH / 31XL2-ZH / FS-10C-2X / Other systems
back ( <- ) or next ( -> )
Select an operation mode:
AMBIENT: Ambient temperature measurement. The operation will be based on PASC
(Proportional ambient temperature system control).
The unit is working in an energy efficiency mode depending on the outside temperature to
operate the heating cable based on an internally calculated duty cycle.
LINE : Pipe/line temperature measurement.
Assignment of sensors: Sensor 1 for heating circuit 1; sensor 2 for heating circuit 2;
a revision of this assignment can be done later in the parameter settings.
back ( <- ) or next ( -> )
Default values are set for each parameter. Change the default values by clicking on the
arrow sign for each value and enter a new value.
back ( <- ) or next ( -> )
Select pipe diameter from range DN 10 up to DN 125.
back ( <- )
The minimum ambient temperature is the minimum expected temperature outside
the building. This parameter influences the duty cycle duration. Use the +/- keys to
select a temperature. Clicking on the "back" icon ( <- ) will store the value and show it in
plumbing settings.
Value Range: From –40°C to 0°C
back ( <- )
Select the temperature using the +/- keys.
The minimum temperature is 0°C and max. temperature is +80°C
back ( <- )
YES:
The test program runs for 30 minutes, during which all parameters will be ignored to
check heating cable and connection on site. You can stop the test program at any time.
