Inputs

Analog Input

The C1050 series controllers are equipped with three general purpose analog inputs. These inputs can be configured to
receive signals of the following types:
• Thermistor (Ω)
• 4 -20mA
When a thermistor is used, the thermistor must be 10KΩ TYPE 3.
Each C1050 analog input is equipped with a fast-switching barrier diode to protect against surges and short circuits.
By default, the C1050-HP analog inputs are set up for thermistor mode. The input signal mode can be changed by setting
jumpers U1, U2 and U3, situated inside the casing, in the desired position:

Temperature Sensors

he C1050 Heatpump controller has three analog inputs that monitor outside air, return air and supply air temperatures
and will integrate these readings into its control sequence. The sensors used are standard 10k type 3 thermistors that
share a single common connection.
Alternatively, the supply air temperature can be retrieved from a zone controller that has its own supply sensor and
belongs to the C1050's network.
The outside air temperature can be also be provided by an alternate source. If a network controller is present on the
network, it can retrieve the outside temperature reading from one controller and distribute it to any other controllers on
the network.
