HEAT RECOVERY SCREEN
(Software Version C.OPT.01.21.307)
OVERVIEW
This screen displays all parameters related to the Heat
Recovery feature. It also allows for setting of the
setpoints applicable to this feature.
The Heat Recovery feature is an optional feature and if
so equipped, it must be enabled on the SETUP Screen.
Once enabled, this screen is accessible from the CON-
DENSER Screen. If the Head Pressure Control feature is
also enabled, there is no separate Head Pressure Control
Screen. Rather, the Head Pressure Control parameters
and setpoints appear on this screen. The screen above
is shown with Heat Recovery, Hot Water Control and
Head Pressure Control enabled in ANALOG Control
Source.
When Heat recovery is enabled, the condenser ow
animation will show ow when either the Condenser
Liquid Flow Switch or the Heating Condenser Liquid
Flow Switch says ow is present. When heat recovery
is disabled, the condenser ow animation is based on
the standard Condenser Flow Switch. This screen also
serves as a gateway to controlling the Refrigerant Level,
Heat Recovery and Head Pressure Control.
A complete explanation of the Heat Recovery feature is
contained in Service Manual 160.54-M1.
