Trimax Control Procedure
1. Press the round INSTALLER button. See Fig. 4.
2. Enter the installer access code “054” by using
the LEFT and RIGHT buttons to select a digit
and the UP and DOWN buttons to change the
digit. Press the OK button to enter the access
code.
3. Press the RIGHT button to highlight the
Manual Operation icon then press the OK
button.
4. Press the OK button while the FAN icon is high-
lighted to manually fire the burner and power
the CH circulator.
An adequate CH load must be present to dis-
sipate the heat generated during the combus-
tion test. If an adequate CH load is not avail-
able, an indirect water heater can be used to
dissipate the heat by creating a DHW call
which will enable the DHW circulator.
5. Press the RIGHT button to adjust the firing rate
to 100% (high fire). Hold down the RIGHT
button to rapidly increase the firing rate.
6. If the combustion levels during high fire are
outside the recommended combustion settings
adjust the THROTTLE SCREW (see Fig. 3)
using a flat-blade screwdriver as follows:
Counter-clockwise adjustment of the THROT-
TLE SCREW at High Fire (100% firing rate):

pressing the LEFT button to adjust firing rate
down to 0% (low fire).
