Addendum Summary
This addendum describes how to enable and use the 2-stage
cooling mode features available with TC-1 firmware version
3.93 and higher.
2-Stage Cool Mode
Basic Description:
In 2-Stage cooling (C2) mode the TC-1 uses a single
temperature probe to monitor glycol temperature
and, based on stage 1 and stage 2 set points,
engages stage 1 and stage 2 relays whenever glycol
temperature is above each stage's respective set
point.
C2 mode is only available while the Extended
Function parameter (EF, accessible under the CC
menu) is enabled.
During programming, C2 mode is indicated by the
illumination of both the COOL and AUTO front panel
LEDs and by the characters “C2” displayed in the
temperature window. During operating mode, the
COOL and AUTO LEDs illuminate while glycol
temperature is displayed in the Temperature window.
In multiple temperature probe applications, the
controlling temperature probe is designated by the CP
parameter (see TC-1 User's Guide).
Each stage's set point (SP1 and SP2) can be adjusted
individually or ramped up and down together while
maintaining their relative offsets.
