All SpaNET spa controls feature a heartbeat LED. This heartbeat LED flashes to indicate the current health/status of the spa control. When the spa control is functioning correctly the heartbeat LED emits a single flash in a constant pulse much like a heartbeat (i.e ON, OFF, ON, OFF etc). If the spa control has encountered an error the heartbeat LED constantly flashes in sequence with the error number being experienced (i.e ER-2 =ON,ON; OFF; ON,ON; OFF etc).The heartbeat LED is located on the mini-din connector end cap of the spa control as illustrated below.
Problem: LCD blank, heartbeat on constantly (not flashing) and pump not priming
Cause: Real Time Clock (RTC) battery flat. Controller has been in storage and has not been powered ON for several weeks and RTC battery has no charge.
Solutions:
1.Check topside panel lead is firmly plugged into the spa control socket labelled “TPAD1” 2. Unplug and re-plug topside panel lead to re-establish connection to spa controller 3. Check for damage to topside panel lead including bent or broken pins on plug
NOTE: The topside panel lead requires the metal of the plug to constantly touch the metal ring inside the TPAD1 socket to form a grounded signal. In some cases the two metal surfaces do not touch properly and it will cause the display to flicker or only operate intermittently. To solve this problem unplug the topside panel lead from the controller. Use pliers to gently squeeze the plug so that it is marginally out of shape, then reconnect to spa controller (refer pictures below).
SpaNET spa controls feature self-diagnostics and scrolling error messages to quickly troubleshoot possible problems. Should the spa control encounter a problem the alarm will beep and the error code/message will scroll across the topside panel screen until the problem is resolved. The beeper will continue to sound for a period of 5 minutes. To silence the alarm sooner press any button on the topside panel and the beeper will be disabled.
If an error condition is experienced all spa functions are shut down and the spa should not be used until the error condition has been resolved. A list of error codes with descriptions of problems and possible solutions has been detailed below for your reference.
NOTE: For most error codes: mains power to the spa control must be turned OFF and then back ON before the error condition will be cleared.
Problem: Heater sensor cable fault
Cause: Heater sensor lead is not correctly connected to spa control or damaged
Solutions:
Problem: Water prime failed – insufficient water level detected in heater tube
Cause: Airlock in pipe work, low water level, dirty filter cartridges
Solutions:
Problem: Heater thermal trip activated - Heater has been active and had insufficient water flow over the element. Low or no water flow has caused the element temperature to exceed 47o C and the spa control has shut down operation to prevent any damage to the heater unit.
Cause: Low water level, airlock in pipe work, closed shut-off valves, dirty filter cartridges, filtration pump operation intermittent or not running at all
Solutions:
Problem: Pool over temperature – temperature sensor reading = > 45'C
Cause: High ambient temperatures (especially in summer months) have caused water temperature to rise above set temp point, Excessive filtration time, Jet pumps have been operating for extended periods with the spa cover still on.
Solutions:
Problem: Heater temperature sensor unable to communicate with spa control
Cause: Heater sensor lead is not correctly connected to spa control or has damaged / bent pins
Solutions:
Problem: In-Pool temperature sensor unable to communicate with spa control
Cause: In-Pool temperature sensor lead is not correctly connected to spa control or electronic fault
Solutions:
Problem: Internal controller fault detected
Cause: Power surge, low or high voltage, water on spa control terminal block, relay problem
Solutions:
