•
Vent Type: Select from unit-type-specific venting options: PVC, cPVC, Polypro or
•
Stainless Steel.
Exhaust Safety: If Enabled, this parameter protects the unit and exhaust vent from
•
excessively high exhaust temperatures. When exhaust temperature exceeds any of
three limits, an action is taken, as shown in the table below. The limits depend on the
vent material specified in Vent Type (Stainless Steel has no limit).

Fuel Type or Primary Fuel (Dual Fuel models only): Choose either Natural Gas or
•
Propane. This option is not available for all unit types.
Secondary Fuel (Dual Fuel models only): Displays the alternative to Primary
•
Fuel.
Blower RPM Display: If set to Enabled the following parameter appears:
•
o Blower Pulses/Rev: Specifies the number of blower pulses per revolution,
based on the tachometer output of the blower. Setting above 0 is only practical in
units with blowers that have a tachometer output. (Range: 0 to 100)
Language: Choose from available language options: English, Spanish, French.
•
Unit of Measurement: Choose the unit of measure the Controller will use, either
•
Metric (°C, lps, Pa) or English (°F, gpm, in. W.C., psi). The corresponding LED
indicator on the Controller's front face, °F or °C, lights (see Figure 6.2.2-1, below).
Temperature Sensor: Specifies the sensor type: PT1000 (the default on all
•
current units) or Balco. DO NOT CHANGE unless replacing a C-More Controller on
