The M1000 Heatpump controller has three analog inputs that monitor outside air, supply air and
return air temperatures (see Figure 3) and will integrate these readings into its control sequence.
The sensors used are standard 10k type thermistors that share a single common connection.
Alternatively, the supply air temperature can be retrieved from a slave that has a supply sensor and
is located on the Masters network.
The M1000 can receive the setpoint and temperature from a specific room when a PL-RSC analog
thermostat is connected to it. The M1000 will then automatically integrate this information into its
control sequence. The setpoint may also simply be set by software. The PL-RSC series room
sensors are connected using a 3-conductor cable (see Figure 4).
