Flamin Systems
was recently asked to design a thermostat to replace one removed from
the market. No other unit in the market emulated, closely enough, the
previously obsoleted unit. A key requirement was software that allows
the user to set all outputs independently, and more importantly, based only on offsets from the setpoint.
This means the user can shift the setpoint and all the related
deadbands shift with the setpoint. We also added a large format, easily
readable, backlit, 20 character by 4 line full alphanumeric,
upper/lower case, display.
This unit was also designed with
options including CANbus communications, RS-485, a realtime clock, and
five buttons,(though only three are presently used). Also included is a
pot input to allow remote analog adjustment. Multiple powering options
are available including 85~260Vac, 47~400Hz with an alternative
stuffing option allowing 10~28Vdc. This unit's software uses a common
temperature sensor for all 4 channels, providing essentially a 4 stage
heating and/or cooling controller. However with a full stuffing four
temperature input channels can be used which would provide 4 separate
cooling zones or four channel control. The temperature sensor is a 100
Ohm platinum RTD so the controllable range extends from -200C(-328F) to
850C(1562F). It has tenth degree resolution!
