Off-Peak Method of Charge Control |
5 |
Sets the method of brick core charging to be used during off-peak (charge) periods. System is configured for automatic charge control which is a value of five (5). |
||||||||||||||||
|
Start Brick Core Charge Set Point |
50°F |
If utilizing automatic charge control as set in C000, this value indicates the outdoor temperature at which the system will start charging. NOTE: If using the Comfort Plus as a "Stand Alone" furnace, the factory recommends a value of 50 (°F)/10(°C). If using the Comfort Plus with a heat pump, the factory recommends a value of 40(°F)/4.4(°C). |

|
Full Brick Core Charge Set Point |
10°F |
If utilizing automatic charge control as set in C000, this value indicates the outdoor temperature at which the system will target a full core charge. |
||||||||||||||||
|
0 |
If using PLC communication, this setting must match the channel setting in the Steffes PLC transmitting device. A value of zero indicates power line carrier communication is disabled. |
|||||||||||||||||
|
Optional Controls Configuration |
9 |
Notifies the unit when Time Clock Module or Outdoor Sensor are being utilized.
|
||||||||||||||||
|
Control Switch Configuration |
1 |
If utilizing power line carrier control, the Steffes Time Clock Module, line voltage peak control, or the utility control switch opens for charging this value should be zero (0). For all other applications, this value should be one (1). |
||||||||||||||||
|
Output Control Configuration |
3100: 2 4100: 3 |
Configures the output controls of the Comfort Plus system. To determine the value, check the options desired from the list below. Then, add the numbers from the "Value" column and enter the sum into this location. Example: Steffes 4100 heating system with a heat pump that energizes the reversing valve for heating, add 3+128 for a value of 131. (Thermostat must be set to energize O in Cooling)
|

|
Charge Factor |
30 |
This configuration should be set to a value of 30. |

|
Heat Pump Compressor Outdoor Lock-Out Temperature for Off-Peak or Anticipated Peak Modes |
5°F |
Indicates the outdoor temperature at which the heat pump’s compressor is locked out and not allowed to operate during an off-peak or anticipated peak period. |
||||||||||||||||
|
Heat Pump Compressor Outdoor Lock-Out Temperature for On-Peak Mode |
5°F |
Indicates the outdoor temperature at which the heat pump’s compressor is locked out and not allowed to operate during an on-peak period. |
||||||||||||||||
|
Minimum Discharge Air Temperature |
90°F |
Sets the minimum discharge air temperature the system targets during a Stage 1 heat call (or Stages 1 and 2 in two-stage Heat Pump Operation). |
||||||||||||||||
|
Time Clock Module Configuration |
C013:244, rest:0:00 |
C013 - C021 Only applicable if utilizing the Steffes Time Clock Module. See C004 above. |
