The EH -800 controller has 4 measurement channels. If an extensi-
on unit EXU-800 is connected to the controller, the controller has 6
measurement channels.
Measurement channel 1 is reserved for outdoor temperature me-
asurement. The controller has its own plug-in for an outdoor tem-
perature sensor. If the controller is used as a constant temperature
controller, the outdoor temperature measurement can be activated
or inactivated at this point.
An H1 supply water sensor is already connected to measurement
channel 2.
Measurement channels 3 and 4 are connected to the controller using
a connecting cord. Select the use for the measurement channels at
this point. You can select a measurement connected to room com-
pensation, a factory set temperature measurement or different alarm
uses (contact information) as well as home/away switch use. “Me-
asurement 3”, “Measurement 4” and ”Alarm” can be freely labelled
according to their use.
Measurements 5 and 6 can be taken into use if an extension unit
EXU-800 has been connected to the controller.

that is common for all measurements (see p. 7).
