Controls

 

Nortec offers control solutions for every humidification application. Options include on/off humidistats for general control applications, modulating humidistats for precise control and remote control of relative humidity through a building management system.


Contact your local Nortec representative for details.


ON/OFF Controls

Nortec on/off controls can be used with all technologies for humidity control and/or humidification safety.

For room humidity control, Nortec offers a return-air duct mounted on/off digital duct humidistat or a wall mounted on/off digital humidistat. Both humidistats come complete with a built-in sensor, a keypad for adjusting setpoint and a backlit LCD display. Features such as outdoor temperature setback and a relay for furnace/circulation fan control ensure safe, energy efficient operation. Accuracies of ±5% RH are expected.

For humidification safety, Nortec offers an air-proving and high-limit control. The air-proving switch is used to prevent humidifying when there is no air movement in the duct. For high-limit control, an on/off digital duct humidistat is used to avoid over humidification of the supply duct.

Modulating Controls

Nortec offers humidistats for room and duct control.

Humidistats provide a demand signal to the humidifier and typical accuracies of ±3% RH are expected with standard conditions. For specialty applications, tolerances of ±1% RH can be achieved. Contact the factory for more information.

Humidistats and transducers can either be wall mounted for room humidity control or duct mounted for room humidity and/or high limit control. Both wall and duct controls come complete with a keypad for configuration as well as a backlit digital display.
