Controls Interface
RLC-SVX09H-EN 147
The Unit View displays the system, control point name,
value and unit of measure. It reflects active setpoints and
allows you to make changes.
Unit View also displays, in real time, all non-setpoint data
organized by tabs. As data changes on the chiller, it is
automatically updated in the Unit View.
Circuit/Compressor Lockout)
In order to lockout a circuit the user must go to the Unit
View/Circuit 1 (or Circuit 2)Tab and then select the Front
Panel Lockout for Circuit 1 and/or Circuit 2.The user can
select Not Locked Out or Locked Out.
Condenser Elevation Configuration - RTUD
Installations
Condenser elevation setting is a required input during
startup of RTUD units. Go to the Unit View/ChillerTab,
select Condenser Elevation setting and enter condenser
elevation in appropriate units. Reference Figure , p. 148.
The shipped default of this setting is 0 and it represents the
distance of the bottom of the condenser, relative to the top
of the evaporator. Use a positive value for the condenser
above the evaporator and a negative value for the
condenser below the evaporator. An estimate to within +
/- 3 feet is required.
