JOHNSON CONTROLS

delta p

Displays the pressure difference between the condenser

and evaporator (condenser minus evaporator). This is

also called the Head Pressure. Only appears when Head

Pressure Control is enabled.

head pressure setpoint

Displays the active Head Pressure Setpoint to which the

head pressure is being controlled. Only appears when

Head Pressure Control is enabled.

heating Condenser Liquid flow switch (Led)

Displays the status of the flow switch in the heating

condenser tube bundle. Illuminates when liquid flow is

present. Otherwise, it is extinguished.

Condenser Liquid flow switch (Led)

Displays the status of the flow switch in the standard

condenser tube bundle. Illuminates when liquid flow is

present. Otherwise, it is extinguished.

pid Control Mode

Only appears when Hot Water Control is enabled.

Displays the function the Control Valve is controlling.

If the chiller is equipped with both Heat Recovery and

Head Pressure Control and both are enabled, there is

not a control valve for each feature. Rather, there is

one common valve that is either performing Hot Water

Control for Heat Recovery or it is performing Head

Pressure Control. It will not be performing control for

both features at the same time. Normally, it will be

performing Hot Water Control unless certain operat-

ing conditions cause it to switch over to Head Pressure

Control. When performing Hot Water Control, “HOT

WATER” is displayed. When performing Head Pressure

Control, “HEAD PRESSURE” is displayed. There are

also conditions under which it is not controlling either

one, in which case “INACTIVE” is displayed. Which

feature will be controlling the valve at any given time

and when it is inactive is determined by operating con-

ditions as shown in the flow chart in Heat Recovery

Section 24 in Service Manual 160.54-M1.

Control Valve output

Displays the position command being sent to the control

valve. If Hot water control is enabled and there is flow

in the Heating Condenser, the valve is performing Heat

Recovery Control. Otherwise, if Head Pressure Control

is enabled, it is performing Head Pressure Control.

Displayed over the range of 0.0% to 100%. The actual

value of the output signal for a given error depends on

whether the PID OUTPUT setpoint is set to DIRECT or

REVERSE. If set to DIRECT, the 0.0% output will be at

minimum; the 100% output will be at maximum. If set

to REVERSE, the 0.0% output will be at maximum; the

100% output will be at minimum. Only appears when

Hot Water Control is enabled or Head Pressure Control

is enabled.

Control Valve Control Mode

Displays whether the Control valve is in automatic or

manual control. Only appears when Hot Water Control

is enabled or Head Pressure Control is enabled.

prograMMaBLe

hot Water Control

(Enabled or Disabled; default Disabled) Allows the

Service Technician to enable and disable the Hot Water

Control for the Heat Recovery feature. When enabled,

Control Valve will control the Return Condenser Liquid

Temperature to achieve the Hot Water Setpoint (see

below).

hot Water setpoint

(65.0 to 125ºF; default 95ºF) Sets the temperature to

which the Control Valve will control the Leaving Heat-

ing Condenser Liquid Temperature. Only appears when

Hot Water Control is enabled (see above).

head pressure setpoint

(15.0 to 60 PSID; default 23.0 PSID)Sets the pressure

differential to which the Control Valve will control the

Head Pressure. When both Hot Water Control and Head

Pressure Control are enabled, the Control Valve will

normally be performing Heat Recovery (controlling to

the Hot Water Setpoint). However, it will switch over

to Head Pressure Control when certain operating condi-

tions are met as shown in the flow chart in Heat Recovery

Section 24 in Service Manual 160.54-M1. Only appears

when Head Pressure Control is enabled.
