2.2.3 Input terminals
The HPM has the following input terminals:
x
Sensor input (PT1000, Nickel1000 or Nickel1000 LG): Only one type of
sensor can be used at any one time and has to be specified during the initial
installation (see chapter “The start-up sequence”).
x
Contact input or counter input (for reading a pulse from a meter).
x
0..10V input for sensors with 0..10V output or for a heat demand via signal
(0..10V=0..150°C). These inputs can also be used as 0..10V outputs (see the
operating manual for more information).

Fig. 2.6: Connection of sensors or contact inputs
A sensor is connected to the assigned terminal and to the sensor ground. Exigo
supports connection of up to 8 sensors. PT1000, Ni1000 and Ni1000LG sensors are
not poled, and it is therefore not necessary to differentiate between which wire should
be connected to the ground and which should be connected to the terminal.
The sensor inputs can also be used as contact inputs.
Room sensor with remote setpoint adjustment
To connect a room temperature sensor with a remote setpoint potentiometer (PAW-
HPMR4), all sensor inputs can be used that are still free and which have no function
once the system diagram has been loaded. The sensor ground and the chosen input
terminals must to be connected to the sensor and the setpoint potentiometer in the
PAW-HPMR4 (the sensor ground will probably have to be bridged).
