AV27 PWM maximum value Depends on OP2 configuration
AV28 Binary Off Delay For the Fan
AV29 Time Proportioned Heating Controller Limit Depends on OP3 configuration
Sequence of Operation
The fan will operate according to the selected fan type as described under Fan Control in the Output
section of this document (on page 32). For hotel applications you may want to define the fan type as
Manual.
The selected heating and cooling outputs will operate according to their type and the controller stage
that they are associated with.
DNT-T103 Only: When the fan type is ‘Intermittent’ the fan will start when the first stage controller
value for heating or cooling becomes greater than 99.9%. When the first stage controllers for heating
and cooling both become less than 1% a delay counter for stopping the fan will be started. Once the
delay time has expired (Setpoint 28, Output 3 Binary Delay) the fan output will be turned off.
6. U
NIT HEATER
This application is no longer supported as of Release 3 firmware for BACstat II products. Use the FCU
application to configure control for a Unit Heater. [And refer to Edition 1.6 for earlier firmware
releases.]

ADIATION & REHEAT – [Application (AV12) = 5]
Function: Control of simple single stage or multi-stage heating, typically using wall fin radiation or
reheat.
