Installer-Supplied Components
The relay output from (1A11) is required to operate the
evaporator water-pump (CHWP) contactor. Contacts should
be compatible with a 115/230V (ac) control circuit. The CHWP
relay operates in different modes depending on Tracer UC800
or Tracer BMS commands, if available, or service pumpdown
(see maintenance section). Normally, the CHWP relay follows
the AUTO mode of the chiller. Whenever the chiller has no
diagnostics and is in the AUTO mode, regardless of where
the auto command is coming from, the normally-open relay
is energized. When the chiller exits the AUTO mode, the relay
is timed open for an adjustable (using TU) 0 to 30 minutes.
The non-AUTO modes in which the pump is stopped include
Reset (88), Stop (00), External Stop (100), Remote Display
Stop (600), Stopped by Tracer (300), Low-Ambient Run Inhibit
(200), and Ice Building complete (101).

• Exceptions noted in paragraphs following
When going from STOP to AUTO the CHWP relay is
energized immediately. If evaporator water flow is not
established in 4 minutes and 15 seconds, the Tracer
UC800 de-energizes the CHWP relay and generates a
non-latching diagnostic. If flow returns (i.e. other system
controlling the pump), the diagnostic is cleared, the
CHWP is re-energized, and normal control is resumed.
If evaporator water flow is lost after it has been
established, the CHWP relay remains energized, the
CHWP relay remains energized and a non-latching
diagnostic is generated. If flow returns, the diagnostic is
cleared and the chiller returns to normal operation.
In general, when there is either a non-latching or latching
diagnostic, the CHWP relay is turned off as though
there was a zero-time delay. Exceptions where the relay
continues to be energized occur with:
1. A low Chilled-Water Temperature diagnostic (non-
latching) (unless also accompanied by an Evaporator
Leaving-Water Temperature Sensor Diagnostic)
OR
2. A starter-contactor interrupt-failure diagnostic, in
which a compressor continues to draw current even
after commanded to shut down.
OR
3. A Loss of Evaporator Water Flow diagnostic (non-
latching) and the unit in the AUTO mode, after initially
having proven evaporator water flow.
