SET WATER HEATER OPERATION
Set Operating Setpoint temperature
1. From the Home screen on the Touch Screen Display press
the MENU button.
2. Under the MAIN MENU options select TEMPERATURES
and then press on 'TANK SETPOINT'.
3. Once the TANK SETPOINT screen appears, adjust the
desired MIN and MAX values using the + and – buttons .
4. Once the desired temperature is set, press the ACCEPT
button to upload the new temperature.
Verify WHR circulator mode
When the tank thermostat or tank sensor calls for heat, the
Control Module will turn on the water heater pump. When the
DHW call for heat ends, the water heater pump will continue to
run for a period of time. This pump delay is set at the factory to 60
seconds. If a shorter or longer delay is desired, the appropriate
parameter in the control must be changed. See the XP Water
Heater Service Handbook for a detailed explanation of this
procedure.
Set clock
The UIM has a built-in clock that it uses for its Setpoint Adjustment
feature and for logging events. This clock must be set when the
water heater is installed, and anytime the water heater has been
powered off for more than 4 hours. Use the following procedure
to set the clock:
1. From the Home screen on the Touch Screen Display press
the MENU button.
2. Under the MAIN MENU options select ECONOMY MODE/
CLOCK.
3. Select CURRENT TIME and CURRENT DATE and set the
current time and date using the + and – buttons.
4. Press the ACCEPT button to set the current changes.
NOTE: The internal clock does not adjust for Daylight Savings
Time and therefore, will require a manual adjustment. The clock
is automatically updated whenever a PC is connected and the
Win Pro-Installer program is started.
Configuration of the Lead/Lag
When installed in a Lead/Lag system, the individual controls must
be programmed for Lead/Lag operation. This is accomplished
by accessing the control parameters under Control Modes and
Lead/Lag.
Select the parameter “Address” under Lead/Lag. Each appliance
in the Lead/Lag system must be programmed with its own
address. The water heater designated as the Leader will have an
address of 0. The remaining water heaters in the Lead/Lag will be
Members and have addresses from 1 - 7. Select the appropriate
address and upload the address into the control. Repeat this
procedure for all water heaters in the Lead/Lag, designating the
Leader control and the Member controls.
NOTE : A tank sensor must be installed when operating XP Water
Heaters in Lead/Lag.
Propane water heaters – verify conversion
1. Verify propane conversion has been completed per the
Propane Conversion instructions.
DO NOT
adjust gas valve outlet pressure. The gas valve is
factory-set for the correct outlet pressure. This setting is suitable
for natural gas and propane, requiring no field adjustment.
Attempting to alter the gas valve outlet pressure could result in
damage to the valve, causing potential severe personal injury,
death, or substantial property damage.
XP water heaters are typically shipped ready to fire on natural
gas. Check water heater rating plate to determine which fuel the
water heater is set for. If set to natural gas, it may be converted
to Propane (LP) by installing an orifice or by making a gas
valve adjustment (see pages 15 and 16). In order to operate on
Propane (LP) gas, an orifice MUST BE installed or a gas valve
adjustment MUST BE made. Failure to comply could result in
severe personal injury, death, or substantial property damage.
CHECK FLAME AND COMBUSTION
1. Turn the main power off to the water heater by placing the
“On/Off” switch in the OFF position.
2. Remove the flue temperature sensor from the flue pipe
connection. Note: Combustion measurements will be made
at this point.
3. Turn the main power on to the water heater by placing the
“On/Off” switch in the ON position.
4. Press the RESET button on the Touch Screen Display. In
Service Mode the water heater will fire at ignition speed and
will then modulate up to full fire.
5. Insert the probe from a combustion analyzer into the hole
left by the removal of the flue temperature sensor.
6. Once the water heater has modulated up to full fire, measure
the combustion. The values should be in the range listed in
Table 24 below. The CO levels should be less than 150 ppm
for a properly installed unit.
If the combustion is not within the specified range, reference
the Troubleshooting section of the XP Water Heater Service
Handbook for possible causes and corrective actions.

7. Once the combustion analysis is complete, test the safety
shutoff device by turning the manual shutoff valve to the OFF
position and ensuring that the water heater shuts down and
registers an alarm. Open the manual shutoff valve and reset
the control, and return to Service Mode.
8. Turn the main power off to the water heater and replace the
flue temperature sensor into the flue pipe connection.
9. Place the water heater back into normal operation.
Replace the flue gas temperature sensor to prevent flue gas
spillage into the room. Failure to comply could result in severe
personal injury, death, or substantial property damage.
