Heat exchanger operating limits:
FWD:
*water temperature: max 100° C
*absolute service pressure: min 1 bar/max 11 bars
Accessories - Hot water coil:
If evaporator water flow is not established in 20 minutes *water temperature: min. +2° C/max. 100° C
*absolute service pressure: min 1 bar/max 11 bars
(for normal transition), the UC800 de-energizes the EWP
relay and generates a non-latching diagnostic. If flow
returns (e.g. someone else is controlling the pump), the
diagnostic is cleared, the EWP is re-energized, and
normal control resumed.
If evaporator water flow is lost once it had been
established, the EWP 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 EWP relay is turned off as
though there was a zero time delay. Exceptions whereby
the relay continues to be energized occur with:

Technical Data
The relay output is required to operate the Evaporator
Water Pump (EWP) contactor. Contacts should be
compatible with 115/240 VAC control circuit. Normally,
the EWP relay follows the AUTO mode of the chiller.
Whenever the chiller has no diagnostics and is in the
08
AUTO mode, regardless of where the auto command
(V/Ph/Hz)
is coming from, the normally open relay is energized.
