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.

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

Any volume equal or below 3000 gallons is considered a
Spa, while any estimated volume above 3000 gallons is
estimated as Pool.
Pool Est 11500 gl
Heat Time 120 min
Spa Est 1000 gl
Heat Time 45 min
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.
Pump Status
Press the DOWN key. When enabled, the Pump Status
screen indicates current pump speed.
Pump Control is compatible with Raypak Variable Speed
