Specifications on this page are taken from the Prolon Humidity Controller datasheet, REV 7.3.1 / PL-DATA-C1050HU-C/F-EN.
The PL-C1050-HU controls relative humidity in a room or a duct. Both humidification and dehumidification sequences are available, with PI control loops holding the setpoint.
The humidification setpoint varies with outside temperature, which keeps the humidifier from driving the space to a level that condenses on cold glass. Unoccupied mode setpoint offsets and safety limits are configurable.
Note the output count: this is the only C1050 in the group with 2 digital outputs rather than 4. Humidity inputs are voltage rather than thermistor, at 0-5 VDC or 0-10 VDC for both return/room and supply humidity.
Best For
- Relative humidity control in a room or a duct
- Humidification with setpoint reset from outside temperature
- Dehumidification triggered by digital output or over the network to a rooftop controller
Key Features
Outdoor reset of humidification setpoint
The humidification setpoint varies according to the outside temperature.
Humidification and dehumidification
Both humidification and dehumidification sequences are available. The dehumidification sequence is configurable and is activated by digital output or by network communication to a rooftop controller.
Supply humidity upper limit
Configurable sequence for a supply humidity modulating upper limit.
Networked data and fan restart
Outside temperature and proof of fan data can be received through the network, and a fan restart sequence during unoccupied mode is available when networked.
Two protected triac outputs
2 digital outputs and 1 analog output, all equipped with resettable fuses.
PI control loops
Proportional-integral control loops maximize performance and hold the humidity setpoint.
