Using Thermostat - LG AHNW146A0 Owner's Manual

Using Thermostat

The term "thermostat", which is widely used in this chapter, is a kind of 3rd party accessory.
LG Electronics does not supply thermostat and it should be supplied 3rd party manufacturers.
Room thermostat can be used for easy and convenience control. To utilize thermostat more
efficiently and correctly, this chapter presents information about using thermostat.
CAUTION
1. NEVER USE 230V AC Thermostat and 24V AC Thermostat at the same time. If used
together, it causes short-circuit and yields power cut-off by circuit breaker.
2. Some electro-mechanical type thermostat has internal delay time to protect compressor. In
that case, mode change can takes time more than user's expectation. Please read
thermostat manual carefully if the product does not response quickly.
3. Setting temperature range by thermostat can be different with that of the product. The
heating or cooling set temperature should be chosen within the setting temperature range of
the product.
