Nortec Control Technology For Smooth Control of Every Humidifier Application
Nortec on/off humidification controls are the trusted match for all humidity control and/or humidification safety. For indoor humidity management, Nortec offers the return-air duct mounted on/off digital duct humidistat or a wall mounted on/off digital humidistat. Both feature innovative built-in sensors, a keypad for easy adjusting setpoint, and a subtle backlit LCD display. To elevate energy efficiency and guarantee safety, the on/off controls include outdoor temperature setback functions and a relay for furnace/circulation fan management which is up to ±5% RH accurate. Since humidification safety is one of Nortec’s highest priorities, air-proving and high-limit controls are available. The air-proving feature prevents humidification when there’s no detectable air movement in the duct. On the other hand, for high-limit regulation, an on/off digital duct humidistat avoids over-humidification of the supply duct.
Humidistats for room and duct regulation function as signal provider for the humidifier, while being supported by transducers sensing relative humidity and functioning as a setpoint control in the humidification system. To be expected are accuracies of ±3% RH with standard conditions, while tolerances of ±1% RH are possible to be achieved for specialty applications.
