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.
5.6
Test the fan
1. Start the fan by setting the value FAN to between 3 - 10V (30 - 100%). Check that the fan is running.
2. Stop the fan by setting the FAN value to 0.
5.7
Checking the four way valve
1. Start the circulation pump by setting the value CIRC.PUMP to: 1 (OPTIMUM not selected), 30-100% (OPTIMUM selected) .
2. Start the compressor by setting the value COMPRESSOR to 1.
3. Start the fan by setting the value FAN to between 3 - 10V (30 - 100%).
4. Check the temperature on the supply line (INFORMATION -> OP. DATA) after a few minutes.
5. Switch the four way valve (FOUR-WAY VALVE = 1).
6. Check that the temperature of the supply line drops.
7. Reset the four-way valve and stop the fan, compressor and circulation pump
