iAIRE will take a customer supplied unit and install a modulating gas valve in a gas heat unit or an SCR controller in an electric heater to allow for the heat to be modulating. This creates a new system that has approximately 10:1 turn down ratio in a gas unit and even higher on an electric heater. This allows for tighter control of discharge air temperatures and closer control of space temperatures if desired. iAIRE has (3) control schemes for control of the modulating heat. These are:
Discharge Air Control (DAT) – The air temperature leaving the unit is controlled to a specific temperature.
Space Air control – The room space air temperature is controlled to a specific temperature.
No control – This has no iAIRE control provided. This form of control is usually used with a customer provided control system that will send a 0-10V signal to the modulating valve or SCR to control temperature.
