11-25-2010, 12:42 AM
hi i am looking to upgrade my businesses commercial type thermostats to a programmable type. The unit i have is a trane x19091229. atleast thats what it seems to be. i cant seem to find any information on the unit much less a manual.
wire colors- red,white,yellow,blue,green
stated terminal designations - hsp,mode(sys/fan),csp, signal common, hsp
im trying to figure out what would be a compatible programmable thermostat.
and what the wiring configuration would consist of.
any info is appreciated!! thanks

There is no DIY help on this forum, but I will tell you that, that thermostat is not a conventional thermostat, and any replacement will need to be obtained by a person with access to Trane parts.

Trane does not use thermostats, they use room sensors. The only way to use a conventional thermostat is with their interface board (available only through Trane Parts). They do offer programmable room sensors, but you are going to have to call a qualified contractor, they will have access to the correct parts depending on which route you choose. From past experience the labor is less to just install a new room sensor vs an interface board and conventional t'stat.

Some Trane units can use either a room sensor or a conventional thermostat without adding an interface board in the unit. A technician who is familiar with Trane units should be able to determine quickly if your equipment can use either. If your equipment can use either, he would then need to determine if a cable with more conductors will need to be installed to accomodate the number of heating/cooling stages and thermostat power requirement.
