6. When Heating does not operate

Turn ON Main Power

Operate “Heating Mode( )” by setting the desired temperature of the remote control is higher than one of the indoor temperature by 2°C at least.

In heating Mode, the indoor fan operates in case the pipe temperature is higher than 28°C.

Check the connector of intake and pipe sensor(thermistors)

•Check the related circuit of RY-4WAY

•Check the indoor room temperature is disconnected or not (about 10KΩ /at 25°C).

•Check the indoor pipe temperature is disconnected or not (about 5KΩ /at 25°C).

Check the DC voltage on the PWB ASSEMBLY

• The details of check are as followings

	• Comp Relay.						• Outdoor fan Relay
