Is your Tstat set for 1CPH? This is a recurring problem with the newer Tstats, but easily fixed. Also, the digital Tstat only register integers +/_ 1 deg so it could really be lower than it reads.Two-pipe Trane vaporvacuum system; 1466 edr

Most stats, especially Honeywell and Emerson, won't deviate from the set temp unless the house really warms up or cools down. A few brands will wait til the display shows 69 before turning the heat on and may run it til 71 appears.0

Without a model number it's hard to look up the install manual. If you still have that it should give directions for setting the CPH to 1 or steam. You could try googling it, also.Two-pipe Trane vaporvacuum system; 1466 edr

Do you have the manual? For steam it needs to be programmed to SL. You can find the manual online.0
