SSC-1D installation guide
The Single Stage Control (SSC-1D) automatically controls the temperature in a room by switching
fans, lamps, or heaters on or off as the temperature drops below or exceeds the temperature set
point.
When the SSC-1D is in cooling mode, it switches on the fans when the temperature exceeds the set
point. When the control is in heating mode, it switches on the lamps or heaters when the
temperature drops below the set point.

Installing the SSC-1D
The SSC-1D must be installed by a qualified electrician.
Before installing or servicing the SSC-1D, switch OFF the power supply at the source.
Install the SSC-1D and all equipment connected to it according to local electrical codes.
Mount the unit on a sheltered, vertical surface, with the electrical knockouts facing
down.
Use a screwdriver to tighten the screws in the enclosure. Do not use a drill or over
tighten the screws; this can crack the enclosure and ruin the watertight seal.
Use the electrical knockouts for bringing wires or cables into or out of the enclosure.
Use watertight strain reliefs or conduit connectors at all cable-entry points.
Before removing electrical knockouts, remove the cover to prevent damaging the
control. Do not make additional holes in the enclosure; this can damage the watertight
seal or components and void the warranty.
Mounting the SSC-1D
1. Remove the cover from the enclosure.
2. Fasten the SSC-1D to the mounting surface
using the fours screws provided.
Wiring the SSC-1D
Refer to the wiring diagram.
1. Set the voltage switch A to the correct position
for the line voltage used.
2. Set jumper Cto the correct position for the
temperature units (Fahrenheit or Celsius) you
want to use.
3. Set jumper Dto the correct position for the
mode (heating or cooling) you want to use.
4. Connect the wires as shown in the wiring
diagram.

Connecting the temperature probe
Follow the guidelines below when connecting the temperature probe.
Do not run the probe cable in the same conduit as AC power cables
Do not run the sensor cable beside AC power cables or near electrical equipment.
When crossing other cables or power lines, cross them at a 90 degree angle.
Using four-zone averaging
The SSC-1D can monitor the temperature in
four different zones. The control takes an
average of the four temperatures and
operates according to the average
temperature.
To use four-zone averaging, you must
connect four temperature sensors to the unit.
Connect the probes as shown to the right.
Extending probe cables
You can extend temperature probe cables to lengths of up to 500 feet. Follow the temperature
probe guidelines and the guidelines below when extending cables.
Use two-wire 18 AWG jacketed cable. Phason recommends Belden # 9408, Alpha # 5052, or an
equivalent. Extension cable is also available from Phason. For more information, contact your
dealer or Phason.
Join the extension cable to the temperature probe cable as shown below.
If the unit operates erratically with the extended probe, run the cable along a different path or
shorten it.
1. Slide three pieces of heat shrink tubing over the wires: one for the red wire, one for the black
wire, and one for both.
2. Strip the ends of the wires and then twist them together.
3. Solder the wires together using rosin-core flux solder—DO NOT use acid core solder.
4. Slide the heat shrink tubing over the solder joints.
5. Shrink the tubing using a heat gun.

Operation
The SSC-1D controls the temperature in a room by switching fans, lamps, or heaters on or off as
the temperature drops below or exceeds the temperature set point. The set point is the desired room
temperature and can be set between 32 and 98°F (0 and 38°C).
When the SSC-1D is in cooling mode, the control switches on the load when the temperature
exceeds the set point.
When the SSC-1D is in heating mode, the control switches on the load (lamps or heaters) when
the temperature drops below the set point.
Switch position Function
Displays the ambient temperature
Allows you to view and adjust the temperature set point
Clears alarms
Allows you to verify if the control is in heating or cooling mode
Allows you to verify if the control is in Fahrenheit or Celsius mode
Setting the temperature set point
1. Press and hold the switch to the right.
The current TEMP SET displays.
2. Turn the knob to the desired setting while holding the switch to the right. The TEMP SET can
be between 32 and 98°F (0 and 38°C).
You must hold the switch to the right while turning the knob. If this is not done
correctly, the display flashes between tS and the temperature display. This means
the knob has been turned without holding the switch. The control will not accept the
new setting until the switch is clicked to the right.

Display alerts
Alert Description
PS The temperature probe or sensor cable has short circuited.
PD The temperature probe is damaged or the connecting wire is broken.
tS
The Temperature knob has accidentally been turned. The display will alternately flash tS
and the ambient temperature. The control will not accept the new setting until the switch is
clicked to the set position.
or
The voltage switch is set to 230 volts, but the incoming power is 115 volts. Check the
voltage switch.
PF The power has been interrupted. The display will flash between PF and the temperature. To
clear the alarm, click the switch to the right. The control will function normally.
Maintaining the SSC-1D
Proper care and maintenance will help your SSC-1D last longer. To prevent damage to the control,
perform the following steps after the first two weeks of operation, and once a year after that.
1. Switch off the power to the control.
2. Remove the cover and check inside for moisture. If there is any moisture, wipe it away using a
dry cloth.
3. Check all cable entry points to make sure they are properly sealed. If they are not properly
sealed, apply silicone sealant around the entry points.
If you need to seal the enclosure, use a sealant that is labelled as ‘non-corrosive’,
‘electronics grade’, or ‘neutral cure’, such as GE Silicone RTV6780B, RTV 142, or
RTV 162.
Do not use a sealant that is labelled as ‘acetic acid cure’ or ‘acetoxy cure’. These
sealants release acetic acid while curing, which can damage the control and will void
the warranty.
4. Check all wires to make sure they are properly connected and that they are in good condition.
5. Fasten the cover to the enclosure and then switch on the power to the control.

Cleaning the SSC-1D
To clean the SSC-1D, wipe the surface with a damp cloth.
Be careful when washing the room using a high-pressure washer. DO NOT spray the
control using a high-pressure washer, this can damage the control and will void the
warranty.
Evidence of moisture damage inside the control will void the warranty.

Phason controls are designed and manufactured to provide reliable performance, but they
are not guaranteed to be 100 percent free of defects. Even reliable products can experience
occasional failures and the user should recognize this possibility.
If Phason products are used in a life-support ventilation system where failure could result in
loss or injury, the user should provide adequate back up ventilation, supplementary natural
ventilation, or an independent failure-alarm system. The user's lack of such precautions
acknowledges their willingness to accept the risk of such loss or injury.
