RP2100 REMOTE CONTROL INSTALLATION
CAUTION: Before installing remote controls to the
RP2100 Digital Heater, read the following:
The Raypak RP 2100 Digital Heater is remote ready in
most cases. The digital liquid crystal (LCD) display
shows the actual pool temperature, operating status,
and service codes (See examples below). The touch
pad on the control panel allows you to select the desired
pool or spa temperature. It also indicates when a remote
system is controlling the heater by displaying REM in
the display. When connecting the RP2100 Digital to a
remote system, identify whether it is a two or three wire
remote system. Select the appropriate instruction listed
below to properly install the remote to the heater.

Important Installation Notes for
Remote or external wiring configuration
• Remote wiring must be run in separate conduit.
• Remote wiring must not be run parallel to High Voltage
lines.
• For runs of under 30 feet, remote wiring should have
stranded conductors with a minimum of 22 AWG,
600V, cable twisting 1.5 to 2.5 and jacketed.
• For runs over 30 feet, the conductors should be a
minimum of 20 AWG, 600V, cable twisting 1.5 to 2.5
inch lay that is shielded and jacketed.
• Maximum cable length of 200 feet.
• For both Two and Three wire remote systems, the
provided P-7 wiring connector must be utilized. Please
refer to the wiring instructions.
Two-Wire Remote Systems:
To remotely select either pool or spa operation (3-wire/2-
function) requires 3 wires to be connected to the heater.
A switch mechanism that will provide contact closure
between HIGH/SPA or LOW/POOL and common, needs
to be supplied. This mechanism can be a 3-way switch
or any other remote control system that provides dry
contact closure for either setting. See remote wiring
instructions on this page.
Two or Three-Wire Remote Operation:
To remotely select a single operating ON/OFF mode (2
wire/single function) requires two wires to be connected
to the heater. This requires a switching mechanism that
can be a 2-way switch or a remote control system with a
single dry contact closure. See remote wiring instruc-
tions on this page.
NOTE: Do Not connect wiring to fireman switch
location.
