The PRT/HW-WTS Kit does the job but there's room for product improvement, time increments could be more granular than the set 30 minute intervals, battery icon doesn't display battery charge level until it's low (so you don't really know how much charge is left), LCD display at eye level is very faint, needs to be mounted lower and viewed at an angle to see it clearly, backlight 'on' time should be configurable, desk stand could be more robust and wall mount would be better if the thermostat could be slide in rather than clip in. On the receiver it would also be more helpful if the LEDs were labeled HW and CH instead of Zone 1 & 2. That aside the design is good, could be great with these details addressed.
