Rinnai I-Series Condensing Boiler Combi Manual 83
Thermostat Usage (Default Seng)
This is the default seng for the boiler. This seng enables the boiler to operate in CH from a call
for heat from the room thermostat or zone controller.
In this seng, the Central Heang buon is not funconal except as an Error Reset or other seng.
Central Heang Buon
This seng enables the boiler to operate via the Central Heang
buon being acve (illuminated).
While the Central Heang buon is ON, the boiler operates
connuously or unl the return sensor on the boiler gives the signal to
cycle o. The burner res up only when supply or return water
temperature reduces. This seng should be disabled when CH is no
longer seasonally needed.
To select Thermostat Usage or the Central Heang buon, follow the steps below:
1. Remove the boiler’s front panel by removing the four screws that secure the panel.
2. Locate the PC Board (lower le side of unit). Locate the DIP switches on the PC Board (see
below).
3. Adjust DIP switch 2 to one of the following posions
• ON - Central Heang ON buon used. Boiler res based on return water temperature
• OFF (Default) - Thermostat Used
4. Press the CH buon on the controller display. The boiler is now in CH mode.

Linked Operaon Between Main Boiler Pump and CH Pump 1
No
Yes (Linked
Together)
This parameter is only in use when DIP switch 2 is in the ON
posion. This enables the linked operaon between the main
boiler pump and CH pump 1. For example, when the main
pump is on, pump 1 is also on. When DIP switch 2 is in the
OFF posion, the pumps are automacally linked.
