Hey Guys, Does anyone here know if these thermostats (5070THPRPG) The 4 zone programable thermostat, can be used to control a starndard ducted split system without being programmed or linked to a C-Bus network, i love the look of this thermostat and i have C-Bus switches throughout the house so i wanted to use this thermostat to control a Ducted Split which can be controlled with just the switching of relays, however from what i gather they need to be programmed and have a C-Bus network to them to maintain a constant time and schedule. Any help would be great. Thanks Chris
