Sequence of Operation
The selected heating outputs will be operated according to their type and the controller stage that they
are associated with. There can be up to three stages of heating, depending on the heating type and
configuration of the outputs. Also, Outputs 1 to 3 may be defined as Time Proportioned instead.

Sequence of Operation
Input 3 represents the built-in humidity sensor and becomes the input to the internal controller. The
adjustable room setpoint (AV6) becomes the humidity setpoint. And the controller proportional band is
used for humidity control, now in units of percent. Output 1 (via AV1) will operate according to its
selected output type and the value of the controller output, typically turning O
N when the humidity is
low and O
FF when the setpoint value has been reached.
OUTPUT FUNCTIONS & TYPES
Regardless of model, any triac outputs are capable of switching up to 24 VAC at a maximum of 0.5 A
each, and may be configured for any of a number of output functions and types. Only the DNT-T221
supports two
0-10v outputs, up to a maximum of 20 mA each. Not all applications support all the options listed.
