Correctly. The box has 4 valves inside that act electrically well. Code 32 refers to the open change solenoid, how do I discard it and where is it located? If in the box it has 4 valves per fabor Nesecito a technical apollo
The box connector has 2 positive cables (1 common for two valves and another common for the remaining two, 2 temperature signal cables and 4 cables that energize the valves, I do not know which of the 4 cables must have energy.
