PARAMETERS DESCRIPTION
SP = Set Point - Desired Regulation Temperature r0 = Differential or Hysteresis
r1 = Lower Set Point Limit
r2 = Higher Set Point Limit
d0 = Humidifying / Dehumidifying Control -
Humidifying: To choose Humidifying Control: Set d0 = Hu. The output is activated when the relative humidity is less than the Set Point (SP) - r0 and disconnected if the relative humidity is > = SP.
Dehumidifying: To choose Dehumidifying Control: Set
d0 = dH. The output is activated when the relative humidity is > SP + r0 and disconnected when the relative humidity is < = SP.
c0 = Minimum Times Between Start and Stop.
c1 = Continuous Cycle Time. The time the load is connected when a continuous cycle is activated. To view the programmed cycle time for display, press the down arrow button for 8 seconds. The display with blink as indicated. The output will be connected during the number of hours indicated by the
c)parameter. To cancel the Continuous cycle, press and hold the down arrow button again for 8 seconds.
Lc | = RH value for 4 mA input. Parameters for use with 4 to 20 mA |
| output probe. |
Hc = RH value for 20 mA input. Parameters for use with 4 to 20 | |
| mA output probe. |
P1 | = Probe Adjustment. Offset degrees to adjust probe. If the probe |
| is not placed in the exact point that is to be measured, use a |
| standard hygrometer and adjust the difference with this |
| parameter. |
P5 | = Probe Type. (Set from the factory.) DO NOT ADJUST. |
H5 = Access to Probe Parameters. (The code is set to 0 from the factory.)
Access to all code protected parameters.
•Press SET for 8 seconds. The access code value 00 is shown on the display. (Unit comes with code set at 00 from factory).
•With the UP and DOWN arrows, code can be set to user needs.
•Press SET to enter the code. If code is correct, the first parameter label is shown on the display (SP).
•Move to the desired parameter with the UP and DOWN keys.
•Press SET to view the value on the display.
•The value can be modified with the UP and DOWN arrows.
•Press SET to enter the value and exit to text parameter.
•Repeat until all necessary parameters are modified.
•Press SET and DOWN at the same time to quit programming or wait one minute and the display will automatically exit programming mode.
LED INDICATIONS
OUT This indicates the load is connected. The system waits for the programmed minimum stop time of the load.
DISPLAY MESSAGES
In normal operation, the humidity will be shown on the display. In case of alarm or error, the following messages will be shown:
ER = Memory Error
--=
In the event an error occurs, the unit follows a fixed working cycle which connects the load for 5 minutes and then disconnects the load for 5 minutes alternately.
