START UP AND SEQUENCE OF OPERATION
SINGLE ZONE WHOLE HOUSE OR STAND ALONE USING THE DEHUMIDIFIER CONTROL
1.Press the ON/OFF button to turn the dehumidifier control ON.. The display will show the current setting, and the dehumidifier blower and HVAC blower (if wired to the HVAC system) will turn on to start sampling the air..
The setting will be replaced by the measured humidity and “AIR
SAMPLING” will show on the display.
2.Use the UP or DOWN button to adjust the humidity setting as desired.. The recommended initial setting is 59%..
3.After three (3) minutes of sampling, the measured humidity will be compared to the setting:
a..If the humidity is above the setting, the dehumidifier compressor turns on and “AIR SAMPLING” will be replaced by “DEHUMIDIFYING”. The compressor remains on until the measured humidity falls 3% RH below the setting..
b..If the measured humidity is below the setting, the blowers turn off and the display returns to showing the RH setting..
4.The dehumidifier will sample again every 60 minutes, or at any time if the humidity setting is lowered..
CRAWL SPACE OR SEALED ATTIC (REMOTE) CONTROL USING MODEL 76
1.Press the ON/OFF button to turn the dehumidifier control ON..
“REMOTE” will show on the display to indicate that a remote control is wired to the dehumidifier..
2.At the Model 76, press the ON button; the Model 76 will display the RH measured at the dehumidifier, and the dehumidifier blower will turn on to start sampling the air..
3.Use the UP or DOWN button on the Model 76 to adjust the dryness level as desired.. The dryness levels are from 1 to 7, with 1 being least dry and 7 being most dry; the recommended initial setting is 3..
4.After three (3) minutes of sampling, the measured humidity will be compared to the setting:
a..If the humidity is above the setting, the dehumidifier compressor turns on and “ON” flashes on the Model 76 display.
b..If the measured humidity is below the setting, the dehumidifier blower turns off..
5.The dehumidifier will sample again every 60 minutes, or at any time if the dryness level is increased..
SINGLE ZONE WHOLE HOUSE OR STAND ALONE USING MODEL 76 EXTERNAL CONTROL
1.Press the ON/OFF button to turn the dehumidifier control ON..
“EXTERNAL” will show on the display to indicate that an external control is wired to the dehumidifier..
2.At the Model 76, press the ON button; the Model 76 will display the measured RH..
3.Use the UP or DOWN button on the Model 76 to adjust the humidity setting as desired.. The recommended initial setting is 59%..
4.If the RH measured by the Model 76 rises above the setting, the dehumidifier will turn on as will the HVAC blower (if wired to the HVAC system). “DEHUMIDIFYING” will appear on the dehumidifier control display to show that the Model 76 is calling for dehumidification.. The dehumidifier and HVAC blower (if on) will turn off when the RH measured by the Model 76 drops 3% RH below the setting..
TWO ZONE – PRIMARY AND SECONDARY
1.Press the ON/OFF button to turn the dehumidifier control ON..
Dehumidification of the Primary Zone follows the same sequence as described to the left for Single Zone, with or without a Model
76 external control installed in the Primary Zone.. The dehumidifier control display will show “PRIMARY ZONE” in addition to
that described to the left when sampling or dehumidifying the Primary Zone.. The zone dampers are energized when sampling or dehumidifying the Primary Zone..
2.The Secondary Zone uses the humidity setting on the dehumidifier control.. During Secondary Zone sampling or dehumidification, the zone dampers are
“SECONDARY ZONE” will show on the dehumidifier control display when the Secondary Zone is either sampling or dehumidifying.. If the Primary Zone had just finished a dehumidification demand, the compressor will continue to run during Secondary Zone sampling to prevent short cycling of the compressor..
The Secondary Zone is sampled immediately after the Primary Zone has finished sampling, or if there is a call for dehumidification from the Primary Zone, immediately after the call has been satisfied..
When a Model 76 external control is installed, the Secondary Zone will be sampled once per hour if there has not been a call for dehumidification from the Primary Zone.. Secondary Zone sampling will also occur whenever the setting on the dehumidifier control is lowered..
