The pool temperature will be controlled by the System
Sensor (S3). The VERSA IC
®
will provide Max Return
protection control using the Pool Return sensor (S6)
and will cycle the burner if the return to the pool
exceeds the Max Return setting. Both the system (S3)
and Pool Return (S6) sensors must be installed using
a drywell and fully immersed into the flow path for
proper operation. Max Delta T (Differential
Temperature) control is also provided and will cycle
the burner if the Max Delta T is exceeded between
Heater Outlet Sensor (S1) and Heater Inlet Sensor
(S2).
In order to enable MIX settings, VERSA
®
DIP #3 must
be set to ON position. Raypak’s Cold Water Protection
system utilizes a variable-flow pumping system to
inject just the right amount of water from the main sys-
tem loop into the boiler loop to maintain the optimum
inlet temperature (S2) as defined in the Installation
and Operating manual for the product being installed.
The variable-flow pumping system will operate in par-
allel with the unit mounted heater pump.
The Heater Pump (P1) runs during any call for burner
operation and is delayed “off” as user-defined in the
SETUP menu after the burner has shut down. The
System Pump output (P2) is enabled to run whenever
the heater is enabled for operation. The Heater Pump
(P1) runs during any call-for-heat. The Heater Pump
(P1) is delayed “off” as user-defined in the BOILER
menu. The System Pump output (P2) is delayed “off”
only when the heater is disabled by opening the con-
nection across the enable/disable at the PIM™.

There is no mode to configure for Pool operation as
this is the only mode available when built as a P model
unit. The System Sensor (S3) and Pool Return sensor
(S6) MUST BE installed in the circulation loop and
functional for heater operation.
Ensure DIP switch #1 and 2 on the VERSA
®
Control
Board must be in the ON position to make program-
ming changes. Prior to setting any DIP switches the
heater must be turned off.
POOL – Cascade
This section covers a cascade of up to 4 P model
heaters for use on direct Pool Water heating systems
with and without CWP using a variable-flow pumping
system. Reverse/return piping is shown and is recom-
mended to ensure balanced flow through each of the
connected units. Primary/secondary piping is the only
method supported by Raypak to ensure proper heater
and system functionality while achieving maximum
system efficiency. The piping configurations below are
representative of a cascade of condensing heaters
without CWP or non-condensing heaters with CWP
provided by a variable-flow pumping system.
NOTE: 0-10VDC firing rate control ignores all
functions except Max Delta T, CWP, Limit and Safety
Switches.
