In the UK you don't really need the temperature sensor if you're going to use the pump to convert from an EPIC system, the wax stat only needs about a minute or so to warm up. The advantages of the sensor is that it is that it cuts the power to the cold starter saving voltage to start the engine, and keeps that power cut whilst the weather is seriously cold and the engine needs more time to warm up.
Without the temperature sensor in place the cold starter is drawing power all the time, so if you turn on the ignition but don't start the engine for a minute or so you'll loose the advantage of the cold starter.
No idea what temperature the sensor switches at. At least 30*c would make sense at that would allow a cold start effect at most ambient temperatures without drawing power at ignition on.
If you don't want to use the cold start at all just don't wire it in, somebody has already slackened off the pull cable to disable the mechanical side on that pump. Assuming your going to use that pump that is.
