As this is a closed system and professionally maintained and requires special coolant, there is no need to
check coolant levels in the expansion tank. If there is any questions as to the operation or perceived
problems please call AYC for assistance.
System Operations
Prior to operating the system, understand that there are three functions that can be achieved. First determine
which of these you want to accomplish.
1.
You want heat only.
2.
You want heat with continues hot water.
3.
You want continues hot water only.
Heat only option:
To operate the system for heat only follow these steps.
First in all three cases the inverter must be on. The inverter provides AC power to the circulating pump and
temperature sensors. If the inverter is not on the system will not work. Remember the inverter runs off of
only on battery and is limited to the charge condition of it. Monitor your usage and occasionally check the
condition of batter charge.
The inverter is located on the bottom left corner of the AC panel and has a push button to turn it on. There
will be a green indicator light showing when the inverter is active.
Next go to the thermostat and using the up down buttons set the thermostat to the desired temperature and
make sure the left/right off/heat switch on the lower left corner of the thermostat is set to heat.
If the switch
is not set to heat, no fans will operate in the system regardless of how they are set individually.
