I have a conventional boiler/radiator setup in my house and an additional zone using a Salus RT500RF (TX) controller for underfloor heating in an extention.

To control this underfloor heating; is it possible to add an additional extension box, in place of the sender, with a awireless thermostat.

This way I can control the whole house in one system

Hope you can help

    Thanks.
    I should probably use a wireless smart thermostat then?

    @stephenjm: I am using the same salus thermostat but I am experiencing 
excessive system inactivity times with worsening of comfort 
and increased consumption. my system is connected via opentherm 
bus. I was wondering if you are having the same experience. 
For me, the type of operation of the thermostat is not satisfactory 
as once the setpoint temperature has been reached, it switches off the 
system until it is lowered but due to the thermal inertia of the system
 this regulation strategy is not good. When the set point temperature is 
reached, a maintenance strategy would be necessary, with small ignitions 
calculated in order to keep the temperature
 reached constant, avoiding useless and expensive swings.
