Programming Instructions
IMPORTANT: If the programming sequence is interrupted for more than 15 seconds or not completed to the blank
screen stage, the unit will automatically revert to the humidity display mode WITHOUT acknowledging any
new values (tamper resistant feature).
B. DIFFERENTIAL(S), HIGH/LOW SETPOINT LIMITS AND CALIBRATION – To program these parameters, press
the "hidden" button located behind the "%RH" symbol (instead of the SET button), and repeat the programming
procedure described in step A.
1. Differential "dIF" – setting a positive differential value will close the NO (normally open) relay(s)
on humidity fall (humidification applications) and open the relay(s) on humidity rise. A negative differential
setting will close the NO relay(s) on humidity rise (dehumidification applications) and open the relay(s) on
humidity fall. Differential is programmable from –30% to +30%. DO NOT SET DIFFERENTIAL AT "0".
2. High and Low Setpoint Limits "HI" and "LO" – allow you to limit the range in which the setpoints can
be programmed. Also, by programming the high and low setpoint limit values to the same number, a
tamper-resistant fixed setpoint is established.
3. Calibration "CAL" – Controller calibration can be programmed +30%. Unit is factory calibrated to a
certified standard.
A. SETPOINT(S) 1. To start the programming sequence, press the SET button once. Unit displays "SP1" (setpoint 1).
2. Press the SET button again to display SP1 value.
3. To program an increase or decrease in SP1, press the appropriate ADJUST arrow.
4. Repeat steps 1 thru 3 for SP2 (setpoint 2, dual stage model only).
5. To complete the programming sequence, press the SET button until the screen
goes blank. After five seconds, the unit will automatically display sensor humidity.
