Description
Selects the schedule format. In non-programmable mode all scheduling functions are
removed from the display.
When enabled daylight savings time follows the US 2007 format. (Begins second Sunday
of March at 2AM and ends on the first Sunday of November at 2AM.
Heat Stage 2 takes the place of this outside air damper output.
Damper output is not available when being used as a fan speed.
0: Output runs continuously when thermostat is not in System OFF Mode.
1: Output cycles with a heat or cool demand.
0: The thermostat will Not activate the fan with a heating demand.
1: The thermostat will activate the fan with heat demand.
Single Speed - White/Orange Lead
2-Speeds - White/Orange & White Brown Leads
3-Speeds - White/Orange, White/Red & White Brown Leads
Reverses the ON/OFF operation for the heat output. NC operation powers on with a
demand. NO opreation powers off with a demand and will be on with no demand unless
main power is removed from the thermostat.
Reverses the ON/OFF operation for the first stage heat output. NC operation powers on
with a demand. NO opreation powers off with a demand and will be on with no demand
unless main power is removed from the thermostat.
0: Remote temperature sensing is disabled.
1: The TW180 uses the remote sensor only for temperature sensing.
2: The TW180 averages the local and remote sensor for temperature sensing.
When using a remote sensor an open or short will turn off outputs and display either
2Ero(open) or 2Erc (closed). Fault detection settings are not used.
Enables fan coil pipe sensor operation. Connect a PECO pipe sensor or dry switch closure
for change over from Summer (cold water) to Winter (hot water) on COOL output (blue
wire). 2-pipe operation uses the COOL output for heating and cooling. Heat 1 is disabled.
4-pipe operation allows heat 1 in summer mode of operation.
Available when SM 110 = 1 or 2
Available when SM 171 = 1 or 2. Changes to Cool when pipe temp is below threshold.
Available when SM 171 = 1 or 2. Changes to Heat when pipe temp is above threshold.
