FLOAT SWITCH

If the Model 1700 is installed in an attic, the unit should be placed in a drain pan with a normally closed condensate overflow safety switch (also known as a float switch). The float switch should be wired to the float switch terminals on the dehumidifier control board. See Figure 18. Remove the jumper at the float switch terminals. The compressor is disabled when the float switch is open. The Model 1700 will continue to ventilate when the float switch is open.

DIP SWITCH DEFINITIONS

MODEL 70 – OFF/ON (SYSTEM SETUP SWITCH #1):

Determines use of internal RH and temperature sensor or use of the RH and temperature sensor on the Living Space Control (Model 70).

MODEL 70-OFF.Uses inlet RH and temperature sensor.

MODEL 70-ON.Uses Living Space Control (Model 70) RH and Temperature Sensor.

Default is MODEL 70-OFF.

HVAC FAN – OFF/ON (SYSTEM SETUP SWITCH #2):

Determines if the HVAC fan activates during a call for dehumidification.

HVAC FAN-OFFposition. The dehumidifier will not activate the HVAC fan during a call for dehumidification; it will however activate the HVAC fan for air cycling and ventilation.

HVAC FAN-ONposition. The dehumidifier will activate the HVAC fan during a call for dehumidification as well as for air cycling and ventilation.

Default is HVAC FAN-OFF.

WHL HOUSE / CONVERTIBLE (SYSTEM SETUP SWITCH #3):

Determines when the dampers are powered open or closed.

CONVERTIBLE position. The damper (DEH) terminals are actuated when the HVAC equipment is making a call for heat, cool or fan and the dehumidifier is making an internal blower call for air sampling or dehumidification.

WHL HOUSE position. The damper (DEH) terminals are actuated any time the dehumidifier is making an internal blower call for air sampling or dehumidification.

The default position is WHL HOUSE.

VENT-AUTO / VENT-TIMED (SYSTEM SETUP SWITCH #4):

Determines if ventilation is restricted based on outdoor temperature

VENT-AUTOposition. The dehumidifier will measure the outdoor temperature (through sensor, part # 8052) to determine if the ventilation damper will open. If the outside temperature is above 100°F or below 0°F the dehumidifier will not actuate the ventilation damper terminals (VENT DAMPER). If the outside temperature is between 0°F - 20°F, the dehumidifier will only actuate the ventilation damper terminals (VENT DAMPER) when the HVAC system is making a call for heat. The dehumidifier will energize the HVAC fan whether or not the ventilation damper opens.

VENT-TIMEDposition. The dehumidifier will actuate the ventilation damper terminals (VENT DAMPER) regardless of the outdoor temperature.

The default position is VENT-AUTO.
