HEAT RECOVERY/HEAD PRESSURE CONTROL SCREEN

FIGURE 10 - HEAT RECOVERY/HEAD PRESSURE CONTROL SCREEN

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/Head Pressure Control 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 CONDENSER 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 Head Pressure Control enabled in the
Local Control Source mode.
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-

Level, Heat Recovery and Head Pressure Control.

is contained in OptiView Control Center – Service In-
structions (Form 160.76-M1).
