Wired or Wireless Thermostat ??.

I have installed a Wireless Receiver with 10 Wireless Radiator Thermostats which gives me independent room control. The query I have is, the old system was 2 zone plus hot water, Tado only offers 1 zone plus hot water. The existing system has 2 wired thermostats, 1 for each heating zone. The thermostats have only 2 wires, will 2 wire's be compatible with Tados wired thermostat. If it's not compatible, will the Tado wireless thermostat work in my case ???.
