Wireless room stat

[dsmart]

Need to find a solution for a pub that has 2 linea 28 se boilers installed they want wireless room stats for the Lounge and bar. Vokera weren't much help on the phone.

RF would be ok, if you can get a good signal to boiler's , would think any make of RF stat would do, where is the time control ?
