5.5 Thermostat Controller Expander

5.5.1 Introduction

The Thermostat Controller Expander (TCE) is accepting the TC as a piggy back device. This allows

the use of the TC+TCE as a standalone device with the possibility of e.g. external power and more

rugged connections. It will also form a more rugged housing for the TC.

(TCE will be designed for Phase 2 of this project)

5.5.3.1 The TCE shall have a service connector of the type 3.5mm stereo-jack

5.5.3.2 The Service connector shall be protected against ESD (8KV for air

discharge )

5.5.3.3 The following signals for the service connector shall be used

1- Power input 3.5 – 10VDC (tip)

2- Serial communication (middle)

3- GND (inner)
