Description

C000

L010

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).

C001

L012

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.

C002

L013

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.

C003

L020

Power Line Carrier (PLC) Channel Selection

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.

C004

L035

Optional Controls Configuration

9

Notifies the unit when Time Clock Module or Outdoor Sensor are being utilized.

C005

L036

Control Switch Configuration

1

If utilizing power line carrier control, the Steffes Time Clock Moduleline voltage peak control, or if the utility control switch opens for charging, this value should be zero (0). For all other applications, this value should be one (1).

C006

L037

Output Control Configuration

2

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 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

L043

Charge Factor

30

This configuration should be set to a value of 30.

NOTE: C008 through C009 configurations are only applicable if the Comfort Plus Hydronic system is being used in conjunction with a heat pump.

C008

L046

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.

C009

L047

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.

C010

L048

Minimum Discharge Air Temperature

90°F

Sets the minimum discharge air temperature the system targets during a Stage 1 heat call.

NOTE: 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, temperatures in °F.)

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 appropriate for the application.

C011

L000

Maximum Outlet Water Temperature

140°F

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°F; C002 = 10°F; C011 = 180°F; C012 = 140°F, then at an outdoor temperature of 30°F, the targeted outlet water temperature would be 160°F.

C012

L001

Minimum Outlet Water Temperature

140°F

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°F; C002 = 10°F; C011 = 180°F; C012 = 140°F, then at an outdoor temperature of 30°F, the targeted outlet water temperature would be 160°F.

C013-C021

L003, L062-L073

Time Clock Module Configuration

C013:244, Rest:0:00

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.
