Heater Checkout Follow these instructions to verify that the ECOMMAND 4 is properly controlling the heater. 1. Check that the ECOMMAND 4 is calling for the heater to turn on as indicated by the "Heater" LED being illuminated. If the "Heater" LED is illuminated, go directly to step 2; if not, then check the following: • The heater is enabled (Configuration Menu/Heater Config.). • The heater temperature setting is at least 2ºF greater than the water temperature (Set- tings Menu / Pool Heater & Spa Heater). • The filter pump is running. • If the pool has solar heat and the solar priority feature is enabled (Configuration Menu/ Solar Config) then solar must be off in order for the heater to fire. The easiest way to force solar off is to go to the Settings Menu / Pool Solar & Spa Solar and temporarily lower the temperature settings below the current water temperature. 2. Check that the heater is running. If not, then check: • Power is supplied to the heater. • The ECOMMAND 4 control output is properly connected to the heater control (see "Heater Control" wiring, page 9). • Some heaters also have internal switches or jumpers that have to be set correctly for remote control operation-refer to the heater manual and also "Heater Control" (page 9). • Heater is turned on ("Kill Switch" is in the "ON" position). • If a heater bypass valve is installed, check that water is flowing through the heater. • The heater temperature setting is set as high as possible (usually 104ºF/40ºC). Also note that some heat pumps actually have be set to the lowest possible temperature. 3. Once the heater is running, you can verify the "heater cooldown" feature (optional - see Configuration Menu/Heater Config.) is operating properly: • Press the "Filter" button once (for 2 speed pumps, this may require 2 pushes of the "Filter" button). • The heater should turn off ("Heater" LED off) and the "Filter" LED will flash to indicated heater cooldown is active. • The display will periodically indicate that the filter pump is on for heater cooldown and show the minutes remaining. • The pump will automatically turn off at the end of the 5 minute heater cooldown period. For more detailed instructions on control and operation of the ECOMMAND 4 system, refer to the Operation Manual. Service Mode Service mode disables all automatic control operation and is intended to be used when servicing the pool system. To enter service mode, push the SERVICE button once on the main unit keypad. This will initially turn all outputs off and then allow you to turn outputs on/off manually at the main display (only). In service mode, the buttons on the optional spa side remote will turn outputs off, but will not turn any output on. Heater control outputs and solar control outputs are prevented from turning on if the water temperature exceeds 104ºF (40ºC). 28 USE ONLY HAYWARD GENUINE REPLACEMENT PARTS
