EOH Operation Example 1
74-5577–33 (US)
EN2B-0184 GE51 R0518 (Europe)
The following schematic diagram illustrates EOH use.
A switching table implements an outdoor air temperature-dependent frost protection
function outside of EOH. When outdoor air temperature is less than or equal to 2C
(36F), the table sets a constant room temperature setpoint (for example 10C [50F]).
The value of the constant is the X2 input parameter of the SWI icon.
Frost protection applies only during the cool-down phase because EOH demands a
0C (32F) flow temperature during this time and the flow temperature setpoint of the
application program that is equipped with frost protection is overwritten.
