Temperature sensor, hot water top
A temperature sensor for hot water top (BT7) can be
connected to GreenMaster-HP via soft inputs for showing
the water temperature at the top of the tank.
The temperature sensor, hot water top (BT7) is connected
to the selected input (menu 5.4, see page 27) on terminal
block X6 on the input card (AA3) which is located behind
the front cover and in a submerged tube on the water
heater.
Temperature sensor, external flow line
If temperature sensor, external supply line (BT25) needs
to be used, connect it to terminal block X6:5 and X6:6
on the input board (AA3).

Room sensor
1. Shows current room temperature in the display on
GreenMaster-HP.
2. Option of changing the room temperature in °C.
3. Provides the option of fine-tuning the room temper-
ature.
Install the sensor in a neutral position where the set
temperature is wanted.
A suitable location is on a free inner wall in a hall approx.
1.5 m above the floor. It is important that the sensor is
not prevented from measuring the correct room temper-
ature, for example by being located in a recess, between
shelves, behind a curtain, above or close to a heat source,
in a draught from an external door or in direct sunlight.
Closed radiator thermostats can also cause problems.
GreenMaster-HP operates without the sensor, but if you
want to read the home's indoor temperature from the
display on GreenMaster-HP the sensor must be installed.
Connect the room sensor to X6:3 and X6:4 on the input
board (AA3).
If the sensor is to have a controlling function, it is activ-
ated in menu 1.9.4.

If the room sensor is used in a room with underfloor
heating, it should only have an indicatory function, not
control of the room temperature.

Caution
Changes of temperature in accommodation
take time. For example, short time periods in
combination with underfloor heating will not
give a noticeable difference in room temperat-
ure.
