4. Use the harness adapter supplied in the accessory
bag labeled as "single-speed pump" to connect the
field-supplied relay to the terminal of the control
board marked as "PUMP" [P5]. Connect the other
end of the harness to the coil terminals of the relay,
as shown in Figure 135.
5. Connect the wires coming from the pump and the
power distribution box to the relay contact terminals,
as shown in Figure 135.

6. By following this configuration, the control board can
operate the field-supplied relay, which in turn supplies
power to the single-speed pump and allows it to turn
on or off.

Protégé Variable-Speed
Pump Control Wiring
The Crosswind V control is designed to operate Raypak
Protégé variable-speed pumps. It comes equipped with
a dedicated communication port labeled "COM" [P12].
To connect a Protégé variable-speed pump to the
Crosswind V, use the RS-485 Modbus harness (P/N
652281).
By default, the variable-speed pump control is disabled.
However, when the option is enabled and set to operate
a "Protégé VSP", the default control mode is to command
the pump using the Raymote app via Wi-Fi. To use this
mode, the heater must be connected to a local Wi-Fi
network to manually command the pump or use online
automation routines. Additionally, the variable-speed
pump can be controlled by the built-in local schedule
with up to 4 periods of operation per day or by the built-
in automatic mode "Heater demand" that commands
the pump whenever the heater needs heat or cool. For
details on the single-speed pump control modes, refer to
section 13 in the Installer menu on page 21.
1. Follow the general instructions for wiring external
devices to run the RS-485 harness from the Protégé
variable-speed pump to the control box of the heater.
2. Connect the keyed circular connector of the pump
harness to the pump. See Figure 136.
Figure 136. Keyed Circular Connector
3. Then connect the other end of the RS-485 Modbus
harness to the terminal labeled as "COM" [P12] on
the control board. See Figure 137.
