Heating
(continued)
Heating will start when the Start differential condition is met and the water temperature
is below the Target Temp. When these conditions are satisfied heating is turned ON.
Example: Water Temperature is 75° F; Target Temperature is 82° F. When the roof solar
collectors temperature exceeds the water temperature by 6° (81° F), the solar valve
rotates. If a solar booster pump is required, this pump will turn on.
When Heating turns ON; the solar booster pump will turn ON and the valve actuator will
rotate. After five (5) minutes the Cleaner Pump Relay will turn on.
• IntelliFlo
SolarTouch controller: Program 2 (Speed 2) solar speed is assigned for solar
heating and cooling. For more about setting Program 2, 3 & 4 see page 12.
Heating will turn OFF under the following conditions:
• Pool or spa has met the target temperature.
• Cloud cover appeared and the stop differentials turn the system off.
•
No more thermal energy available.
•
External time clock turned system off.
When Heating turns OFF:
•
The valve actuator will rotate.
• Solar booster pump will turn off.
• If IntelliFlo Pump is being used as either a filtration pump or a solar booster
pump, RPM will change and resume to the timed program set speed (RPM).
This could take up to one (1) minute.
•
IntelliFlo and IntelliPro pump connected and communicating with SolarTouch
Controller: The pump is not being controlled by SolarTouch controller at this
time.
• Pressure Cleaner pump will remain on only if the external time clock cycle is
still on.
Solar Hold Feature for Heating and Cooling:
Using a Variable Speed Pump
When SolarTouch controller calls for heating or cooling and solar heat is
available, the IntelliFlo Variable Speed Pump will ramp up to the RPM's assigned
to Program 4 (Speed 4 - default speed is 3110 RPM). The solar valve will
maintain the closed position for the first five (5) minutes, then the solar valve will
move to the "open" position and the pump will continue to run an additional five
(5) minutes. After these 10 minutes, the pump reverts to the assigned speed for
Program 2 (Speed 2).
Cancel Solar Hold: To cancel the Solar Hold feature, press either the UP or
DOWN arrow button for approximately 3 seconds on the SolarTouch controller.
Note: If pool is plumbed with a pressure cleaner pump (i.e. pool cleaning
system), this pressure pump will turn off for five (5) minutes when the valve
actuator turns on. This allows the air in the solar collectors to be evacuated
from the system without damage to the pump.
