Renting an apartment with boiler/radiator heat. Seems like when the
heat goes on, it stays on too long. The old Robertshaw thermostat
(can't see a model #) has a "longer-shorter" sliding switch inside it.
Am I correct that moving it in the "shorter" direction will cause the
heat to stay on for shorter periods? If I set the thermo at 65
degrees, I would want it to turn off at 67. Thanks.
