Maintenance Required for Boiler Controller
Check that boiler operation is consistent with the steps in the
Touchscreen Boiler Controller Manual.
Check that water temperature targets and setpoint is satisfactory and
have not been adversely amended.
Check the operating history using the boilers Logs menu and Error Logs
menu.
The controller tracks the duty cycle of the boiler in each of the 4 loads
separately. This information can be used to adjust the water
temperatures of each load.
If a problem exists with the controller, see

7.1.8 Water

Checks for Water in the Boiler
Check water pressure and temperature.
There should be no noticeable change if boiler is functioning normally.
Check for any noise in the system.
Check water piping for damage or leaks and repair as needed.
Check the water pressure. Pressure should be stable when the boiler is
firing and the water temperature is rising.
If pressure rises sharply, consider replacement of expansion tank.
Check also for noise at high fire, which may signal water quality
problems.
Water chemistry shall be of a quality generally accepted as suitable for
hydronic applications.
Ensure any direct "city fill" water connections are left in the closed
position to minimize exposure to leaks and flooding.
