MODEL S77 – REMOTE CONTROL AND WIRING
NOTE: Use 18-22 AWG wire for control wiring�
Humidity can be controlled using the internal dehumidifier control, a
Model S77 control or a different external control like a thermostat�
Without an external control, the dehumidifier will turn on its blower for
three minutes every 15, 30 or 45 minutes depending on how often the
unit is set to sample the air� The dehumidifier can also be set to sample
the air continuously (see AIR SAMPLING on page 11)� The blower is
turned on to get a representative reading of the room relative humidity�
A shorter sampling period reduces the duration of any humidity spikes
that might occur when neither the air conditioning nor the dehumidifier
are running� To reduce energy consumption the sampling time can be
set to a longer period�
Installing an external control eliminates the need to run the dehumidifier
blower for sampling as the control is constantly measuring the humidity
close to the canopy� When the humidity level rises above the setting,
the dehumidifier is turned on�
To install the Model S77 control:
1. Unplug the dehumidifier or turn off power to the circuit at the
breaker or fuse�
2. Run a 4-wire thermostat cable (use 18–22 AWG wire) from the Model S77 to the control of the dehumidifier�
3. Trim about 1/4" of insulation from the end of the wires on each end� Insert the wire into the terminals as shown in FIGURE 11 and tighten to
secure�
4. Restore dehumidifier power� There is a delay of three minutes after restoring power before the dehumidifier will respond to the control�
5. Go to REMOTE CONTROL on page 10 to configure the dehumidifier control to respond to the Model S77�
The Model S77 will measure the relative humidity and turn the dehumidifier on and off to control the humidity level to the desired setting� The
humidity setting can be adjusted from the control while the display allows easy access and monitoring of the humidity level in the space� It is
recommended that the Model S77 be mounted at/near canopy height� Shield the Model S77 from direct exposure to HPS or LPS lighting�
Press the ON button on the Model AS77 to turn on the control� The UP/DOWN arrow buttons are used to set the desired humidity setting� At all other
times, the Model S77 will display the measured humidity level� Reference the Model S77 Installation and Operating Instructions for set-up�
ALTERNATE EXTERNAL CONTROLS
An 8800 Series thermostat can be used to control the HVAC equipment, and for dehumidifier control in place of the Model S77� The 8800 Series
thermostat has Wi-Fi capability so the conditions in the room can be monitored at any time from any location� Additionally, up to four remote sensors
can be mounted near the canopy and connected to a single thermostat� The four humidity measurements can be averaged and the thermostat will
turn on the dehumidifier based on the averaged value�
Reference the thermostat Installation Instructions and Owner's Manual for wiring, set-up and operating details�
