Arm Override (continued)
Arm Override arm switch must be active, so when the reel is raised the heaters will automatically turn off.
Additionally, the system must also be seeing a flow rate (GPM) from the flow meter before the heaters will run.
**For system priming
and diagnostics, the arm switch can be overridden by the “ARM OVERRIDE” button on
the controller. Activating that button will cause the 2way valve to close and allow flow to go through the heaters
regardless of the lift arm position.
Warming Valve (Slider)
•
Active
Warmup Valve
by sliding the
button right. ON will display and appear
in Blue.
•
The Warmup Valve button will stay
activated until it is either manually
turned off by sliding the button to the
left, or until the Output Temp has
exceeded 200F, at which time the
warmup valve will automatically
deactivate.
The 2way warmup valve is located towards the rear of the machine in between the heaters. The valve is
on the outlet side of heater #2 and is normally closed. When activated on the main screen of the control,
it opens and allows pressurized flow that has gone through the heaters to be returned to the supply tank.
When the heaters are activated and heating water, the warmup valve, when opened, will allow heated
water to be bypassed back to the supply tank until the water temperature reaches 200F.
Once the water temp reaches 200F, the warmup valve will automatically close and shut off on the main
screen, forcing the heated pressurized water out to the reel. The warmup valve is uses for initial priming
(allowing bypass water back to tank) and for initial heating of the system so water does not need to be
sprayed on the ground until after the temperature has reached 200F.

Target Temp / Output Temp (Display)
Target Temp can be adjusted. The recommended temp is approximately 240F degrees.
Operating Temp Status
The Operating Temp Status will display the area will show if the temperature of the water in the burner is at
an adequate temperature by displaying Low, Ok or High.
Low
- Temp under 205 degrees
Ok
- Temp 205-270 degrees
High
- Temp above 270 degree
