Heat - The first stage of heating will be energized for three minutes, then the first and second stages (if a second stage exists) will turn on for an additional three minutes. During the first stage of heating, the HEAT ON icons will be displayed. During the second stage of heating (if one exists), the “2” next to the “On” will be displayed if the system has a two-stage compressor (A2, h2, or H2 unit types). The “auxiliary heat on” icon will be displayed if the second stage is electric heat (HP unit type). For Hybrid Heat installation or heat pump installation, only 1 stage of auxiliary heat is available. Any staging of auxiliary heat must be managed by the furnace or fan coil.

On the non-programmable models, pressing the features button shall toggle the state of the humidify output.

Installer test for cooling is the same as described for heating above. COOL ON will be displayed during cooling in Installer Test Mode. While the cooling test is active, the dehumidify icon shall be displayed if the dry contact has been configured as a DH output. On the programmable models, pressing the button below the dehumidify icon shall toggle the state of the dry contact output. On the non-programmable models, pressing the features button shall toggle the state of the dry contact.

In a heat pump application, when the mode is set to “em heat” the auxiliary heat will turn on for 3 minutes. The clock display will count down from 180 to 0 during this test.
