Test reversing valve (if installed) for hot water
1. Activate the reversing valve by setting the value REV.V. HOT WATER to 1.
2. Check that the indicator on the reversing valve's upper side changes position.
5.4
Test the auxiliary heater
1. Start the circulation pump by setting the value CIRC.PUMP to: 1 (OPTIMUM not selected), 30-100% (OPTIMUM selected) .
2. Start the auxiliary heater by setting the value of present EXT. AUX. HEAT to 1.
3. Check that the auxiliary heater works by exiting the MANUAL TEST menu and
enter the INFORMATION -> OP. DATA menu and check that the temperature of SUPPLY LINE rises.
4. Return to the menu MANUAL TEST and stop the auxiliary heater by setting EXT. AUX. HEATER value to 0.
5. Stop the circulation pump by setting the SYSTEM CIRC. PUMP value to 0.
