Hi All,

We are doing HVAC design. for the HVAC system already we are using A27A+S27A controller with one A99 sensor for the heating/ cooling system. but its analog type.

Now we need digital type (The setting of the thermostat, have to do it digitally).

we need for 5 stages. if anyone know this Digital type model thermostat, please provide details on it.

Thanks,
Dasan

Any PLC (http://www.moeller.co.uk/easy_500.htm) will do that!

Hi
Thanks for your reply....

If we use PLC need to do prog. it take some time also quite expensive. so, we are looking ready to use type one.

Talk once to Regin in Sweden http://www.regin.se/index.php?/se/Regin-System.html and they're rather cheap with their products. If we need something like this, always Regin for 3 reasons: good product, good price and outstanding support.

goshen, those controllers are to control racks for refrigeration systems and not for a temperature control of a building with a HVAC system.
