The EQJW 125 controller is used for weather-compensating flow temperature
control of a heating circuit. An additional room temperature connection is
possible. The controller changes the operating status in accordance with the
switching commands that are entered, on a time-dependent basis.
It has an anti-frost function, an automatic summer time change-over function,
an anti-jamming feature for the pump and a floor drying function.
A communication interface allows connections with other devices and with a
Modbus control station (also via modem), or automatic transmission of fault
messages to a mobile phone as SMS messages via modem.
A rotary switch allows immediate mode changes and direct access to the
main settings. An input knob makes it easy to change the device's settings.
