FUNCTIONS
DIAL/SYMB.
STAGE 1
Set Desired Room Temperature (DRT) for the room. All
other start points refer to this temperature.
Setting for the target humidity level in the room. For
use with optional humidity probe.
•
Differential for Fan #1. This is where you set how many
degrees the fan takes to increase from minimum to
full speed.
8 motor curves to help you make sure the motor runs
most efficiently (see owner’s manual for list).
Sets the minimum speed of Fan #1.
Sets a % for the 1st fan to speed up to remove
humidity.
Timer setting for 1st stage fan. OFF means fan does
not run below DRT. ON fan runs continuously at
minimum speed below DRT. A % means fan runs for
that % of the timer period.
Duty Cycle Timer. This sets the timer period in minutes.
Remember, you set the run time, not off time.
Stage 2 Relative Set Point. DRT plus this setting is
when the second fan starts at minimum speed.
Not Used
Differential for Fan #2. This is where you set how many
degrees the fan takes to increase from minimum to full
speed.
8 motor curves to help you make sure the motor runs
most efficiently (see owner’s manual for list).
Sets the minimum speed of Fan #1.
Not Used
Heat Stage Relative Set Point. DRT minus this setting
is when the heater starts. This stage could also be a
3rd fan stage if desired (see owner’s manual).
Differential for heater. This is where you set how many
degrees the heater runs once it started.
Ramping. This setting is the number of degrees that
you want the temperature to drop each day when set.
This setting is the limit to the ramping. This is the
coolest temperature you want the controller to keep
the room.
This setting records the lowest temperature in the
room. It can be reset each day.
Lo Alarm Set Point. A contact is built into the controller
for the alarm.
This setting records the highest temperature in the
room. It can be reset each day.
Hi Alarm Set Point. A contact is built into the controller
for the alarm.
This is the current room temperature.
This is the current room Humidity reading. The display
will read F2 if Humidity is not used or if humidity in the
room is lower than 40%.

Note: As relative humidity increases above set point, Fan #1 minimum speed will increase to reach high
humidity speed (2nd) at 10% RH above set point.
