Temperature Control
Temperature control setpoint on the module can be
adjusted as described in the following sections. Some
modules with temperature control also include a
three-digit display on the printed circuit board to
facilitate adjustments and troubleshooting.
A separate automatic gas shutoff device is not
required in a system that uses this control to meet
requirements for CSA International ANSI Z21.87 and
UL 353.
The overall range of the setpoint is model-dependent
but is within 140°F to 220°F (60°C to 104°C) with a
default to 180°F (82°C). Select devices may have
different ranges.
Adjusting Settings for Models
with “On-Board” Display
To discourage unauthorized changing of settings, a
procedure to enter the adjustment mode is required.
To enter the adjustment mode, press the UP, DOWN,
and
I
buttons (see Fig. 1) simultaneously for three
seconds. Press and release the
I
button until the
parameter requiring adjustment is displayed.
Display
In the RUN mode, status items and parameters are
viewable. For example, to display setpoint, the control
will flash “SP” (setpoint) followed by the temperature
(i.e., 135), followed by °F or °C.
To read settings, press and release the I key to find the
parameter of interest. For example, press and release
I
until setpoint (SP) is displayed, followed by a three-
digit number, i.e., 220, followed by °F or °C. Pressing
the
I
button again will display the (bt) Boiler
Temperature followed by a three-digit number and the
corresponding degree designator. See Display
Readout.
