Need advice  on my thermostat 

[MikaelKrantz]

Looks like it could be TTS-SD-LCD-4-2

It is a Smart Sensor (TTS-SD-LCD-4-2). It is not a thermostat but a 3 wire space temperature sensor that has the capability of displaying information. It is used with i2 and b3 Andover controllers in a Continuum or EcoStruxure system.  I have attached the user's guide. TCX, LCX and SCX are legacy prefixes for controllers They were all changed to i2 and b3.
