The spa heater stopped working recently and here's where I am:
I cannot start the spa heater from the remote control unit that's mounted inside the house. When I push "spa heat" on the controller, the spa heat is enabled (little green light turns on) but the pump does not start (nor do the electric valves out by the pool equipment automatically rotate from pool mode to spa mode).
Before, when the spa heater worked properly, when the "spa heat" mode was pressed the pump automatically started, the heater would fire up, and the valves would rotate from pool mode to spa mode.
I am able though to go to the Aqualink control box (out by the pool equipment), switch the unit into "service" mode, and push the "spa mode" and "heater" buttons - and the valves turn into the right position and the pump and heater fires up like normal.
I guess if I am not able to figure out why the remote isn't doing it's job, I can always go out to the controller and manually fire everything up - but it sure would be nice to be able to use the remote from inside the house.
Any ideas or advice would be appreciated!
