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
“

”
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).

All Comfort Plus Hydronic Systems (5100 Series)
8
Enables compressor control if there is a "COOL" call during a peak (control) time.
32
If it is a peak (control) period and the Comfort Plus Hydronic receives 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 C010 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.
C011 and C012 configurations must be set
for the hottest temperature zone in the
installation. C011 is the highest tempera-
ture 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 tempera-
ture 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 tem-
perature 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 tem-
perature of 30 degrees, the targeted outlet water temperature
would be 160 degrees.
C013-C021 Time Clock Module Configuration - These configura-
tion 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.
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 water
temperatures are appropri-
ate for the application.
