Auto
mode (Heat Pump Only)
In "AUTO" mode the operating mode is
changed automatically from "HEAT" to "COOL"
and vise versa, depending on the room temperature (Tr)
and the operating set temperature. If the present operating
mode is "COOL" • The operating set temperature
is the same as the user set temperature (Tos = Tus). •
The unit will operate with the "COOL" mode until
the room temperature decreases below the operating set
temperature by 3.5 ºC. In this case the "AUTO"
mode will change from "COOL" to "HEAT".
ie Tr <= Tos - 3.5 ºC or Tr <= Tus - 3.5 ºC
If the present operating mode is "HEAT"
• Its operating set temperature is below the user
set temperature by 1.5 ºC Tos = Tus - 1.5 ºC
• The unit will operate with the "HEAT"
mode until the room temperature increases above the operating
set temperature by 3 ºC. In this case the "AUTO"
mode will change from "HEAT" to "COOL".
ie Tr >= Tos + 3 ºC or Tr => Tus + 1.5 ºC
