SET LO LIMIT
65.0°F
Day Setpoint Low Limit
• This is the lowest Setpoint allowed
• Range: 10.0°F – 100.0°F Default: 65.0°F
SET HI LIMIT
80.0°F
Day Setpoint High Limit
• This is the lowest Setpoint allowed
• Range: 10.0°F – 100.0°F Default: 80.0°F
TEMP. UNITS
FEHRENHEIT
Termperature Units
• Fahrenheit or Celsius
• Default: °F
NIGHT HEAT SET
62.0°F
Night Heat Setpoint
• PCM will maintain this heating Setpoint when unoccupied
• Range: 10.0°F – 100.0°F Default: 62.0°F
NIGHT COOL SET
83.0°F
Night Cool Setpoint
• PCM will maintain this cooling Setpoint when unoccupied
• Range: 10.0°F – 100.0°F Default: 83.0°F
PRO. BAND
2.0°F
Proportional Band
• The Proportional Band is the temperature range through which the controller calculates a
0-100% load
• Range: 0.5°F – 25.0°F Default: 2°F
DAY DIFF.
1.0°F
Day Differential
• This is the maximum allowed “error” on either side of the room Setpoint before the controller
will enter its heating or cooling proportional bands
• Range: 0.5°F – 25.0°F Default: 1.0°F
CONTROL FROM
THERMOSTAT
Control Source
• Thermostat: Controller uses thermostat temperature and Setpoint to determine room load and
control
• Analog Input: Controller uses 0-10VDC inputs to determine room load and control. Use this
control source type for a 0-10VDC signal by others.

SUPPLY AIR TEMP
50.0°F
Supply Air Temperature (S.A.T.) readout
• Shows current thermistor probe reading
• Range: -59.0°F – 300.0°F
• “No Probe” means no sensor is connected
NEUTRAL MODE
FORCE COOL
Neutral Mode
Controls Supply Air calculations by the PCM
NOTE: Default mode is “Force Cool”. This will be used 99.9% of the time.
• Neutral Mode: Dynamic
- When Supply Air Temperature (as measured on thermistor input) is below room temp, it is
considered cold
- When Supply Air Temperature (SAT) is above room temp, it is considered hot
- NOTE: There is a 2 degree differential on either side of the current room temperature
which would equate to Neutral Supply Air if the SAT fell within this range.
• Neutral Mode: Conventional
- Uses hot/cold switch points which are hard set below
- Not recommended
• Neutral Mode: Force Cool
- PCM Default
- Controller assumes cold supply air at all times (despite any reading of T1 Thermistor input)
- This is useful by allowing the T1 thermistor input to be used for monitoring only
• Neutral Mode: Force Heat
- Control assumes hot supply air at all times
- Not recommended
HOT SWITCH
0.0°F
Hot Switch - Only active/visible when Neutral mode = Conventional
• Only active/visible when Neutral mode = Conventional
• PCM will consider the supply air warm if at the hot switch temp or above
• Default: 0.0°F – PCM defaults to Cool supply air at all times
COLD SWITCH
0.0°F
Cold Switch - Only active/visible when Neutral mode = enabled
• Only active/visible when Neutral mode = Enabled
• PCM will consider the supply air cold if at the cold switch temp or below
• Default: 0.0°F – PCM defaults to Cool supply air at all times
