General
Read these instructions carefully. Failure to follow them could damage the product or cause a
hazardous situation.
Select thermostat location
Select a location for the
thermostat approximately 1.5 m
above the floor on an internal wall,
and in the location that requires
heating.
DO NOT install the thermostat
where it can be affected by:
- draughts (hallways, regular
accessed doorways etc.)
- hotspots (direct sunlight,
above fireplaces/heaters,
warm air ducts etc.)
- deadspots where air does
not circulate freely (alcoves,
corners, behind doors etc.)
Installing the thermostat
Before installing the thermostat
make sure the electrician has
preinstalled the RJ45 cable.
1. Take the thermostat out of the
box, and remove the wall plate
from the face plate.
2. Connect the adaptor provided
to the RJ45 cable.
3. Push everything back into the
wall and secure the wall plate
to the wall.
4. Secure the face plate to the
wall plate.

Batteries, wallplate, date and time
Installing batteries
1. Install the two AA alkaline
batteries supplied on the back
of the thermostat.
2. Locate and remove the tab
labelled ‘Remove’. This tab
MUST BE removed in order to
set the real-time clock.
Mounting thermostat to
wallplate
1. Align the terminal screw
blocks with the pins on the
back of the thermostat.
2. Push thermostat straight onto
the wallplate until it snaps into
place.
Setting calendar and time
This thermostat is designed, under
normal use, to automatically keep
current time and day in memory
for up to ten years once the
calendar is set. There are two ways
to set the calendar and time for
this thermostat.
- setting date/time when
thermostat is first powered
- setting date/time after
thermostat is already
functioning
Setting date/time when
thermostat is first powered
When the thermostat is first
powered, the display is ready to
set the calendar and time. The
thermostat proceeds through a
sequence of setup screens.
Setting date/time after
thermostat is already
functioning
Use the installer setup (next page)
to set year, month, and day—refer
next page

Thermostat conguration
To configure the settings for the thermostat:
1. Press and release the ‘System’ key.
2. Press ‘System’ and ‘Done’ keys simultaneously and hold keys for approximately five seconds—until the screen changes.
3. When the display changes, release the keys—the thermostat will display the first setup setting 0120.
4. Use the up and down keys to change the settings and select Next to go to the next step (you can also press Go Back to
review and change the previous setup number).
5. Once the system has been configured, press Done to save the settings.
There are 42 possible thermostat setup numbers and four installer tests. For the purposes of this installation guide we have
listed only those that are relevant to the Rinnai iHeat system. These are categorised as follows:
For numbers that display, but are not listed in the table (0610, 0660, 0690, 0695 etc.), select ‘Next’—these are not required to
setup the iHeat.

0680 Temperature control heat 2 1 = less aggressive Set to 1 to reduce Infinity starts and allow room
temperature to vary slightly
2 = standard
3 = more aggressive Set to 3 to control room temperature more, but Infinity
will start more often
0685 Recovery heat temp. rate 5 0-20 °F/hour This parameter determines how quickly the room
temp. is changed ahead of the programmed time so
the room will be at the desired temperature. High
values will likely cause the fan to run at high speeds,
which could increase air movement noise. For
example, if the programmed temp. is set to 22 °C at
6am and 0685 is set at 15, the iHeat system could run
at maximum at 5:30am to heat the housethis could
potentially be disruptive. Rinnai recommends leaving
the setting at 5.
0700 Temp. display offset (refer p. 8
for further information)
0 -1.5 °C to 1.5 °C
-3.0 °F to 3.0 °F
This is a calibration adjustment. This can be changed
so the temperature displayed matches an existing
reference thermometer that a customer may have.

Further information on preoccupancy purge (0185)
This feature is available only when the thermostat is configured as a programmable schedule, and when a fan is
used. The fan will run 1-3 hours before the occupied schedule starting time to circulate air.
Further information on temporary occupied duration limit (0535)
While in programmable mode, an override button is available to perform a temporary override. In 0535 the
override time can be limited; 0 = no limit, 12 = override limited to 12 hours.
Further information on temperature display offset (0700)
Sometimes we receive enquiries from customers stating the room temperature is different to the temperature
they are seeing on their remote thermometer. One way to address this is by adjusting the temperature display
offset in 0700.

Troubleshooting table
Symptom Possible cause Action
Display does not come on. Thermostat is not being powered. Check for 24 Vac between C and RC.
Temperature settings do not
change.
The upper or lower temperature limits were
reached.
Check temperature setpoints.
Check setup numbers 0600 and 0610; modify as needed.
The keypad is fully locked. Check setup number 0670 to change keypad options.
Heating does not come on. Thermostat minimum off-time is activated. Wait five minutes for the system to respond.
System selection not set to heat. Set system selection to correct position.
System type selection is incorrect. Check setup number 0170 and make sure 8 is selected.
Thermostat is calling for heat
but no heating is running.
Heating equipment is not operating. Check wiring.
Check setup number 0170 and make sure 8 is selected.
Verify operation of equipment in system test mode.
Heat does not turn on. Heating equipment failure. Check for 24 Vac at the equipment on the secondary side of
the transformer between power and common. If voltage is not
present, check the heating equipment to find the cause of the
problem.
Check for 24 Vac between the heat terminal (W)) and transformer
common. If 24 Vac is present, the thermostat is functional. Check
the heating equipment to find the cause of the problem.
Loose or broken wire connection between
thermostat and heating equipment.
Check for 24 Vac between the heat terminal (W)) and transformer
common. If voltage is not present, check wire connection (loose
or broken) between the thermostat and the heating equipment.
If the appliance cannot be made to perform correctly please contact Rinnai (0800 TO RINNAI)
