C006 Output Control Configuration - Configures the output controls of the Comfort Plus Hydronic 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. If not used in conjunction with a heat pump or air
conditioner, the value in this location should be set to two (2).
Value Option Selected
2 All Comfort Plus Hydronic Systems (5100 Series)
8 Enables compressor control if there is a "COOL" call during a peak (control) time.
32 If a peak (control) period and a cooling call, the compressor will turn off and on in 20
minute intervals (off 20 minutes, on 20 minutes, off 20 minutes, etc.).
128 Interfaces Comfort Plus Hydronic with a heat pump that has a reversing
valve which is energized for heating.
C007 Charge Factor - This configuration should be set to a value of 30.
C008 through C009 configurations are only applicable if the Comfort Plus Hydronic system is
being used in conjunc
t
ion with a heat pump.
C008 Heat Pump Compressor Outdoor lock-Out Temperature for Off-Peak or Anticipated Peak Modes
- Indicates the outdoor temperature at which the heat pump’s compressor is locked out and not allowed to
operate during an off-peak or ant
i
cipated peak period.
C009 Heat Pump Compressor Outdoor lock-Out Temperature for On-Peak Mode - Indicates the outdoor
temperature at which the heat pump’s compressor is locked out and not allowed to operate during an on-
peak period.
C010 Minimum Discharge Air Temperature - Sets the minimum discharge air temperature the system targets
during a Stage 1 heat call if using an air handler.
C011 and C012 configurations must be set for the
hottest temperature zone in the installation. C011
is the highest temperature the system will target
and C012 is the lowest temperature the system
will target during a heat call. Outdoor reset is
done using these two temperatures. (See graph.)
C011 Maximum Outlet Water Temperature - The value set indicates
the maximum outlet water temperature to be targeted. The targeted
outlet water temperature is affected by the values in C001 and
C002. For example, if the value in C001 = 50; C002 = 10; C011
= 180; C012 = 140, then at an outdoor temperature of 30 degrees,
the targeted outlet water temperature would be 160 degrees.
C012 Minimum Outlet Water Temperature - The value set indicates
the minimum outlet water temperature to be targeted. The targeted
outlet water temperature is affected by the values in C001 and
C002. For example, if the value in C001 = 50; C002 = 10; C011
= 180; C012 = 140, then at an outdoor temperature of 30 degrees,
the targeted outlet water temperature would be 160 degrees.
C013-C021 Time Clock Module Configuration - These configuration settings are used to configure the peak
control times when utilizing the optional Steffes Time Clock Module. Refer to the installation and
configuration instructions included with the module for more information
.
208V SYSTEMS ONlY:
In standard configuration, Steffes heaters are dual rated for 240V and 208V power connections.
The heaters are factory configured for 240V. If the control circuit is operating on 208V power, the
value in location 28 (l028) must be changed to 5.
CAUTION
Risk of high temperature
water. Can cause property
damage. Improper water
temperature settings can
result in damage to the floor
covering. Make sure the
maximum and minimum wa-
ter temperatures are appro-
priate for the application.
