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 PRES-
SURE 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.
Heat Recovery cannot be used simultaneously with
Heat Pump Duty. When Heat Pump Duty is enabled,
Heat Recovery is automatically disabled and locked.
When Heat recovery is enabled, the condenser flow
animation will show flow when either the Condenser
Liquid Flow Switch or the Heating Condenser Liquid
Flow Switch says flow is present. When Heat Recov-
ery is disabled, the condenser flow 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
OptiView Control Center – Service In-
structions (Form 160.54-M1)
.
Requires a login access level of SERVICE.

tions and explanation of all programmable
