PART 11: START-UP PROCEDURES FOR THE INSTALLER

A. PROGRAMMING FOR THE INSTALLER
This section describes each parameter the
installer can access to customize the settings of
the Mod Con Boiler for a particular installation.
These system limits should not be changed by
the user. It is important to document your set-
tings within this manual after you program the
sytem parameters so this will be recorded for
future reference. Record settings in Fig. 11-1.

NOTE: If you toggle beyond parameters of con-
nected boilers, the display will go into the next
function value.
D. TEST MODE
This function is intended to simplify the gas valve
adjustment if needed. Listed below are the rec-
ommended limits on each Mod Con Boiler and the
Combustion Settings. Automatic modulation does
not take place when the controller is in Test Mode,
only temperature limitation based on the Mod Con
Boiler Central Heating set point occurs. The user
can increase or decrease the fan speed by press-
ing in either the { S 1/-} or { S 2/+} keys.
To activate the Test mode, press the { S 2/+} and
{ S 3/Program} key together for 1 second. Once acti-
vated, you will see in the display { S er} and the ac-
tual fan speed. The measurement of the combus-
tion levels should always be taken at the highest
and lowest fan speed. After 20 minutes, the Test
Mode stops automatically. To exit Test Mode press
{ S 1/-} and { S 2/+} key together for 1 second.

B. PROGRAM ACCESS
To start, press down and hold the { S /3} and { S /4}
simultaneously for three seconds. The display will
change to |000|. Then, with your { S 1/–} key on the
display, press down until you see |925|. This is the
pass code. To confirm that the pass code is cor-
rect, you will need to press and hold the
{ S 3/Program} for 1 second to confirm. If the pass
code is entered incorrectly, the controller program
function will be cancelled and the control returns
