Vent Temperature
Press the DOWN key. The Vent Temperature screen
indicates the temperature sensed in the vent.
Vent Temperature Vent Temperature
Figure 42. Vent Temperature
NOTE: If the sensed flue temp exceeds 390°F (199°C),
the heater will shut down on a vent temperature fault. If
the sensed flue temp is less than 175°F (79°C), the unit
may condense.
Flow Monitoring
Press the DOWN key. By default, the Flow Monitoring
screen indicates the estimated flow when unit is heating.
When optional flow sensor is installed, this screen can be
configured to display flow sensor readings. See page 32
to configure the Flow Sensor input.
NOTE: Ideal water flow rate for a heater is 40 GPM or
higher.
The HX Flow Estimate only considers water flow
through the heat exchanger. Ideal flows through the heat
exchanger are:
• 264 BTU unit is 7 to 14 GPM
• 399 BTU unit is 10 to 19 GPM

Estimated Volume and Heat Time
Press the DOWN key. The Pool Volume and Heat Time
screen indicates the estimated pool volume in gallons and
heat-up time in minutes.
Press the DOWN key again. The Spa Volume and Heat
Time screen indicates the estimated Spa volume in gallons
and heat-up time in minutes.
Any volume equal or below 3000 gallons is considered a
Spa, while any estimated volume above 3000 gallons is
estimated as Pool.

Figure 44. Estimated Volume and Heat Time
NOTE: Volume and heat time estimations are based
on single heater supplying a body of water of constant
volume. Multiple heaters, combined heat sources or
interconnection of multiple body of waters may cause
wrong calculations.
Protégé Pump Status
Press the DOWN key. When a Protége variable speed
pump is connected to the heater and communication
is enabled, the Pump Status screen indicates current
pump configuration.
By default, Pump Control is disabled. See page 32 to
select and configure Pump Control.

Auxiliary Output
Press the DOWN button. The Auxiliary Output screen
indicates current status of the auxiliary relay output.
For operation verification of the auxiliary relay, press
SERVICE and MODE keys simultaneously for 3 seconds
to toggle output state between ON and OFF.
AUX output works as a "switch" that can be turned On/Off
with Raymote app online scheduler.

NOTE: Auxiliary output (port P9) is a dry contact output:
It requires external power supply to energize connected
devices. Do not connect directly to an application that
requires more than 3 Amps. For more details see Section
13, Auxiliary Control Output on page 81.
