Sequence of Operation
The primary purpose of the 345 is to provide power to a
Reset Module 420, 421, 422, or 423, and to provide power
to other tN4 devices such as tN4 Thermostats or tN4
Setpoint Controls.
Single Zone Application
A basic application allows a 345 to connect to a reset module
and to a single tN4 Thermostat or tN4 Setpoint Control to
operate single zone systems. The auxiliary pump is used
to operate the system pump.
