8 INITIAL TEMPERATURE SETTINGS
*Note – All set points refer to the CX34 return (inlet) temperature, and implies a leaving (outlet)
temperature of ~10°F cooler(cooling)/warmer(heating) than what you set.
For example if you want heating output to be ~100°F you would set the heating target to 90°F. Default
setting for cooling should be 54°F, therefore the leaving (outlet) temperature would be around 44°F.
Standard settings would be as follows: Heating, set at 30°c (86°F) return for radiant (for ~supply temp of
95F) , or 35°C (95°F) return for fan coils or fan coils + radiant (for ~ supply temp of 105F).
For cooling mode the standard setting would be 12°C (54°F) to get ~44°F outlet temperature.
Detailed settings as follows:
