General Behaviour Although fully configurable, the Prolon C1050 humidity controller monitors dedicated inputs and uses pre-established control sequences to drive dedicated outputs to control standard humidification or dehumidification equipment. These sequences can be fully optimized to obtain the best results for each type of system.
The second is a by sending a network based signal to any Prolon Rooftop controller. The Prolon Rooftop controller will then take the necessary steps to begin dehumidification. A humidity sensor can optionally be installed in the supply duct, which then enables high humidity limit control. Humidi- fication also stops when the outside temperature becomes too warm.

The example on Figure 3 shows the switches 1, 2 and 4 on the ON position. So the corresponding values are 1, 2 and 8, giving an address sum of 11. (1+2+8=11) The Prolon network allows a maximum of 127 addresses, therefore 127 controllers. Figure 3 - Addressing Dipswitches...
The C1050 Humidity Controller has 2 separate communication ports offering the same functionality on each. Both act as ports for incoming Modbus communications from other Prolon devices or interfaces, such as a Network Controller or remote computer with Prolon Focus software.
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) • 0-5V • 4 -20mA • 0-10V When a thermistor is used, the thermistor must be 10KΩ TYPE 3.
Relative Humidity Sensors The C1050 Humidity controller has two inputs dedicated the relative humidity readings in the room (or return duct) and the supply (optional). This information is then integrated into its control sequences. The sensors used must provide a 0-5VDC signal.
(Output 4 and Output 5). Output 4 is an ON-OFF triac output and Output 5 is an analog 0-10VDC modulating or pulsing output, which follows a proportional and integral algorithm (PI). This PI function is fully customizable via the Prolon Focus software.

Typical Connection of the Analog Output Two types of configuration are possible: 1) The C1050 powers the load and provides a control signal: 24 VAC power (From terminal block #2 of the controller) Controlled 0-10v Load Figure 13 - Connecting the Analog Output (Controller Powered) 2) The C1050 only provides the control signal to the load, which is powered by an external source: External 24 VAC...
Power Source The Prolon C1050 controller is powered by a 24 VAC power source connected using the "COM" terminal and the "24 VAC" terminal. The common for all inputs and outputs are the same as the power source’s common (exception: when an out- put is set to passive, the common for this output will not correspond to the power source common).
