Brute Elite Boilers and Water Heaters

When Outdoor Reset is enabled, and the outdoor

temperature falls between the maximum and

minimum outdoor temperatures (70° and 32° in

the example above), the setpoint will be adjusted

down by about 1° for every 2° increase in the

outdoor temperature. For example, if the outdoor

temperature rises by 10°, the Outdoor Reset function

will adjust the setpoint down by about 5°. (This

ratio between outdoor temperature and water

temperature is adjustable.)
When you set up the Outdoor Reset feature, you

can set the “turning points” on the adjusted setpoint

curve. If you go back to Fig. 91, the Outdoor Reset

screen, you see that the system records these values:

Enable -

Enable = Outdoor Reset feature turned on

Max. outdoor temp. -

If the outdoor temperature reaches this value

or above, the system will use the Low Water

Temp value as the setpoint. In the example

shown in Fig. 91, the Max. Outdoor Temp.

is set to 70°F. If the outdoor temperature is

70°F or above, the system will use 100°F

(the Low Water Temp.) as the setpoint.

Min. outdoor temp. -

If the outdoor temperature reaches this value

or below, the system will not compensate

for the outdoor temperature. In the example

shown in Fig. 91, the Min. Outdoor Temp.

is set to 32°F. If the outdoor temperature

reaches 32°F or below, the system will

use the normal Lead/Lag System setpoint

(120°F in this example).

Low water temp. -

If the outdoor temperature reaches the Max.

Outdoor Temp. or higher, the system will

use the Low Water Temp value as the new

setpoint. In the example shown in Fig. 91,

the Max. Outdoor Temp. is set to 70°F. If

the outdoor temperature reaches 70°F or

above, the system will use the Low Water

Temp. value (100°F) as the setpoint.

There is one other part of this system, and it is

located on a different screen:

LL CH setpoint -

On a system set up for Outdoor Reset, this

will be the maximum water temperature

setting. This is located on the main Lead/

Lag Configuration screen.

Boiler Control thermostat Demand

(This is a Lead/Lag function – do this once for the whole Lead/

Lag system. Make the connections to the controller set up as
the Lead/Lag Master – usually the Primary controller on Boiler

1.)

1. Supply the controller which is acting as

the Lead/Lag Master (usually the Primary

controller on Boiler 1) with a thermostat

closure from the Building Automation

System or multiple boiler control. Connect to

terminals 5 and 6 on TB7.

2. Adjust the Lead Lag Central Heat setpoint.

Note - Bradford White offers “gateways” to

allow connections to BACnet, LON, and other

communications protocols. See Section 9.6.

Job m - Building automation or multiple

Boiler 4-20 ma Setpoint Control

(This is a Lead/Lag function – do this once for the whole Lead/

Lag system.)

In this type of installation, the CH Setpoint is

changed or modulated by a source outside of the

boiler. The low limit of the 4-20 mA signal (4 mA)

sets the low limit of the setpoint, and the high limit

of the 4-20 mA signal (20 mA) sets the high limit of

the setpoint.

1. Supply the controller which is acting as

the Lead/Lag Master (usually the Primary

controller on Boiler 1) with the 4-20 mA input

from the Building Automation System or

multiple boiler control. Connect to terminals 3

and 4 on TB7.

2. On the Lead/Lag Master settings, change the

setpoint source to 4-20 mA.
