Thermostat Question
« on: January 26, 2017, 07:39:51 AM »

Hi, I have a White Rodgers 1F78 on my boiler.  It's a programmable thermostat.  It works fine but seems to kick on and off very often (like 5-7 times per hour).  I was reading in the manual that there is a wire I can clip to make it go longer before cycling:

Hydronic (Hot Water or Steam)
Heating Systems
This thermostat is set to operate properly with a forced-air heating
system. If you have a hydronic heating system (a system that
heats with hot water or steam), you must set the thermostat to
operate properly with your system.
The factory default setting is forced air heat. Clipping jumper
W905 on the circuit board will produce a longer heating cycle
which is normally for hot water or steam (hydronic) systems. Both
settings produce a very accurate temperature control and can be
set to your personal preference. As received, the thermostat
cycles the system just under 1˚F. With W905 clipped, the system
cycles at approximately 1.5˚F.


Should I do this or just leave it be?  I would try but there will be no way to reattach after clipping it without soldering it back.

Thanks!
