2. Connect the field-supplied valve actuator harnesses
to the terminals of the control board marked as
"VALVE 1" [P19] and "VALVE 2" [P20]. Note that the
rating of the control contacts is 0.75A at 24VAC. See
Figure 134.

Single-Speed Pump Control Wiring
The control is designed to operate a single-speed pump
with an output of 24VAC at a maximum of 0.75A. To
switch power and energize the pump, a eld-supplied
24VAC relay is required with common and normally-open
terminal(s) rated per pump specications.
By default, the single-speed pump output is set to be
controlled from the Raymote app using Wi-Fi. In this
mode, the heater must be connected to a local Wi-Fi
network to manually command the pump or utilize online
automation routines. Additionally, the single-speed pump
output can be controlled by the built-in local schedule
with up to four periods of operation per day or by the built-
in automatic mode "Heater Demand," which commands
the pump whenever the heater requires heat (or cool).
For more details about the single-speed pump control
modes, please refer to section 13 of the Installer menu
on page 21.
1. Check the power requirements of your single-speed
pump to determine the necessary power source.
Most pumps run at either 120V or 240V.
2. Follow the general instructions for wiring external
devices to run the pump power cables and power
source wires from the pump and power distribution
box to the control box of the heater.

3. Install a field-supplied relay inside the control
box. See Figure 136. The relay shall have a
coil for 24VAC, and contact terminals rated to
the current specifications of the pump. The next
components are recommended for this application
a. For devices that require less than 10 amps, use
an OMRON LY2F AC24 (Raypak Kit # 008784F) or
similar relay.
b. For devices that require 10 amps or more, use an
OMRON G7L-2A-BUBJ-CB AC24 or similar relay.
