I am not sure if the TPI control is self learning.

If you can not live with the overshoot for a few days just reduce the set temperature until it learns.

Thanks, your explanation made it must easier for me to understand. Will be happy to upgrade now.

I will be staying with my non wifi version as I would miss room optimal start very much.

Thread #16 here, yesterday.

So with the next update we loose zone optimal start time? If so I will not be updating. Optimal start is one of the best things about Evohome.

I have my dehumidifier in the kitchen, it tends to dehumidify the whole house if the kitchen door is left open.

A dehumidifier is a good investment. I never have condensation problems.

In the winter I wish to leave 1 radiator on for my cat when we are away. How is the best way to do that using Evohome?

Have a look at Edyn as well.

What is the advantage of upgrading from the old monochrome Evotouch?

Unfortunately it is just on and off control.

Does anyone know if it is possible to have a thermostat with either PID or fuzzy logic control to send a RF or wifi signal to an electric plug to switch on a 1KW heater?

You could buy a radiator thermostat which does time and temperature such as

Honeywell HR25 Energy Radiator Thermostat Programmable .

1 radiator only working. Please see if you get the temperature oscillations I get.

Assume or another word expect a signal to be sent to the boiler when heat is needed. No signal sent when 1 radiator in operation and temperature is above set point-0.5C. eg. set point 21C only when...

Normally this is not a problem, other radiators in the house are demanding heat so keeps the room temperature within 0.1C. Only in the evening when only the sitting room radiator is on do I get this...

I think there is a bug because I assume a signal would be sent to the boiler when heat is needed, not waiting until the room temperature is 0.5C below the set point.

When only 1 radiator is demanding heat from the boiler, no demand signal is sent until the room temperature is 0.5C below the set up. This causes the room temperature to oscillate.
Please can you...

He did not reply to me either.

Rameses, with only 1 radiator on, have you managed to test on your system whether a demand signal is sent to the boiler when the room temperature is between 0.5C below the set point and above.

Rameses, please test it with 1 radiator running on your system, thanks.

I have just bought a temperature data logger and will be able to show exactly what I mean.

The radiator is cold, the temperature has been above the set point in the afternoon, only begins to warm up 0.5C below the set point. Changing the cycle rate would not change the problem of no demand...

No, what ever the weather the temperature of the room has to fall 0.5C below the set point before heating is demanded. This effect is only seen when only 1 radiator is demanding heat.
