ST-2E / ST-3E

If you are looking for a Thermostat for the master zone on your ST-2E / ST-3E zone boards here is a list of Thermostats that have the separate "O" and "B" connections that you are going to need for the master zone. Remember the ST series boards are master/slave (Winter/Summer manual changeover) so you are going to need these two connections on your zone 1 thermostat for your board to work correctly.
