1. DESCRIPTION
The
MT-514
e
is a temperature controller for cooling or heating applications. It has an internal
audible alarm (buzzer) and an output for alarm control that can also be configured for electric defrost,
hot gas defrost, fan or as a second compressor that will act in parallel with the main one. The minimum
and maximum temperature record is displayed at the touch of a single key
;
(Flatec). Another
available feature is the shutdown of control functions, making it possible for the
MT-514
e
to
operate only as a temperature indicator. And through an intelligent function blocking system, it prevents
unauthorized persons from changing the control parameters.
Product is compliant with UL Inc. (United States and Canada).
