‘MAINTENANCE’ menu contains data to control the Motorized Gas Valve by meaning of boiler’s pressure and PID
algorithm .
MAINTENANCE (password: CACADCB)
Setting Description
PID_P
‘P’ coefficient for PID algorithm. Range: 0 to 99.9. Default = 5. Step 0.1.
PID_I
‘I’ coefficient for PID algorithm. Range: 0 to 99.9. Default = 1 .Step 0.1.
PID_D
‘D’ coefficient for PID algorithm. Range: 0 to 99.9. Default = 0. Step 0.1.
PurgeDelay Purge Delay (please see Fig.) Range: 0 to 255 sec. Default = 30 sec. Step 1sec.
PsPurgeDly Post Purge Delay (please see Fig.) Range: 0 to 255 sec. Default = 15 sec. Step 1sec.
Pressure Stp
Maximum boiler’s pressure set point. Range 0 to 35 psi. Default = 2psi. Step 0.1psi
LowFlameRate Starting point before Flame modulation. can start and Heating Cycle can complete. Range 0% to 100%.
Default = 15%. Step 1%.
SamplingRate PID algorithm sampling rate. Range 1 t0 255 sec. Default = 12 sec. Step 1sec.
9. High Pressure Processing
There are three operational modes the controller can react on the High Pressure: ‘AUTO’, ‘MAN SET’, and ‘MAN ON’.
In the ‘AUTO’ and ‘MAN SET’ mode of operations the controller will finish current operational Cycle and will not start the
next until (PR 2) <= PRESSURE_SP (0.2 psi hysteresis).
In the ‘MAN ON’ mode the controller will close the fuel valve to 0%.If the boiler was turned OFF before changing the
operational mode to” MAN ON” it wouldn’t turn the boiler ON until the pressure become less than the Set-Point minus
.2psi

10. Calibration Procedures
The temperature sensor, pressure sensor, and motor current loop interface must be calibrated after the initial system
installations or after the parts replacement. The OPLC-2100 facilitates the calibration procedure. To enter the calibration
section of the menu, select
SET CALIBRATE and then enter password. Following table provides explanations for the
calibration procedure.
1. Select CAL OutDoorTemp. and press Enter
2. The upper line of the display indicates mode of operation (“CAL”) and
