11.12 Test Mode
11.12.1 Entering Test Mode
System can enter Test mode in two ways:
 Automatically when the following conditions exists for 30 minutes continuously:
o Mode = Cool, Set point = 16, Room temperature = 27±1, Outdoor temperature =
35±1
Or
o Mode = Heat, Set point = 30, Room temperature = 20±1, Outdoor temperature =
7±1
 Manually when entering diagnostics with the following settings:

o Mode = Cool, Set point = 16
o Mode = Heat, Set point = 30
11.12.2 Unit Operation in Test Mode
