Product description

Humidity control with 5 programs (menu driven) and 4 relays with separate on/off switching contacts.

The humidity control works with two sensors in separate rooms to measure the relative humidity and temperature.

Based on these values, the control system determines the absolute humidity and the respective dew points.

Room fans for supply and exhaust air can be directly controlled via built-in potential-free relays.

Applications: measuring humidity and temperature, automatic or manual ventilation, drying or humidification of rooms such as wine cellar, kitchen, sanitary room. Delta-T cooling. TF switch. Controlling equipment for drying and humidification.

Also check the Humidity and Temperature switch.

Applications

Humidity control with 5 programs

The main menu allows you to choose from five built-in programs:

Measure + display for each channel of: temperature, relative humidity, dew point, absolute humidity
Ventilating damp areas, such as (wine) cellars. Control of suction and/or exhaust fans and automatic prevention of condensation.
Cooling with outside air. Control of fan(s) when outside temperature is lower than inside temperature. Adjustable time delay to avoid commuting.
Climate control for controlling fan(s), heating and cooling equipment, with extensive timer functions.
Manual operation of each of the 4 relays separately.

The sensor cables may be extended up to 50 m. The control system includes wire break monitoring for both sensors. The housing is suitable for wall mounting on a 35 mm DIN rail.
