>> Carrier Crusade gas furnace
>> Carrier Comfort Zone Center control box near furnace
>> Carrier Comfort Zone 4-zone controller/timeclock
>> Zone dampers: PEI / AirPax

>> In case anyone cares about the problem motivating this

>> studs near the furnace, gets 24 volts AC from the furnace,
>> and is supposed to supply 10 volts DC to the thermostat,

>> volts with a regular period of about 0.5 second. The
>> circuit boards in the "Comfort Zone Center" look clean,
>> and no components are smoking, oozing, or making crackling
>> noises.

>> So,
>> 1. Should I pay $2934 to replace this controller?
>> 2. Should I consider the style of controller that
>> takes input from four thermostats, instead
>> of reading four actual temperature sensors itself?
>> 3. Should I be looking at X-10 systems? RS485? Can

>> and provides a browser-based interface?
Yes cost is $500.00 per channel and you do the installation
