Electrical Application 346 E1 Description: The Power Manager 346 provides power to a reset module. An on-off Bus 1 Demand signal is provided by non-communicating equipment. The 346 receives a Bus 1 Demand and sends a tN4 message on the tN4 Bus 1 to activate the heating equipment.
PAGE 5
Electrical Application 346 E2 Description: The Power Manager 346 provides power to a reset module and up to three mixing expansion modules. The 346 allows zone managers to be connected to each tN4 bus. As an option, Bus Demands can be used to call for heat on a tN4 Bus. This allows a mixture of tN4 communicating and non-communicating devices to call for heat.

Wiring the Control Terminals 1 - 33 This section explains how to wire individual devices to the Power Manager 346. For step by step wiring refer to the terminal number on the right of the page. • Before wiring ensure all power is turned off and take all necessary precautions. • Install the supplied wiring compartment barriers by sliding them into the grooves provided to isolate the low and high voltage wiring. • Strip all wiring to a length of 3/8 in. or 10 mm for all terminals.
PAGE 7
Terminals 13, 14, 15 tN4 Bus 3 • Connect Bus 3 tN4 terminal (13) to Bus 3 tN4 on the Reset Module. • Connect Bus 3 C terminal (14) to Bus 3 C on the Reset Module. • Connect Bus 3 tN4 (terminal 13) to the tN4 terminal on the Mixing Expansion Module. • Connect Bus 3 C (terminal 14) to the C terminal on the Mixing Expansion Module. • Connect R (terminal 15) to the R terminal on the Mixing Expansion Module.
PAGE 8
Wiring the Auxiliary Pump Inputs Terminals 4 - 15 The 346 has three Auxiliary Pump outputs that are activated once 24 V (ac) is applied to the Auxiliary Pump input from any one of the R terminals. Either Mixing Expansion Modules, tN4 Thermostats, or tN4 Setpoint Controls can activate the Auxiliary Pump inputs. Auxiliary Pump 1 to Mixing Expansion Modules Terminals 4, 6, 7 • Connect the Aux Pmp1 terminal 4 to the Mixing Expansion Module System Pump terminal.
PAGE 9
Auxiliary Pump 3 to Mixing Expansion Modules • Connect the Aux Pmp 3 terminal 12 to the Mixing Expansion Module System Pump terminal. • Connect the C terminal 14 to the Mixing Expansion Module C terminal. Terminals 12, 14, 15 • Connect the R terminal 15 to the Mixing Expansion Module R terminal. Auxiliary Pump 3 to tN4 Thermostats Terminals 12, 14, 15 • Connect the Aux Pmp 3 terminal 12 to the tN4 Thermostat W terminal. • Connect the C terminal 14 to the tN4 Thermostat C terminal.
PAGE 10
Wiring the Auxiliary Pump Outputs Terminals 25 - 32 The 346 has three Auxiliary Pump outputs that are activated once 24 V (ac) is applied to the Auxiliary Pump input from any one of the R terminals. Note: For pumps larger than the control’s rated capacity, an external isolation relay must be used. Auxiliary Pump 1 Terminals 25, 26 • Connect the pump’s line in (L) to the Pmp terminal 25. • Connect the pump’s neutral (N) to the N terminal 26.
PAGE 11
Testing the Auxiliary Pump Inputs Terminals 4 - 14 1. Remove the front cover from the control. 2. Use an electrical test meter to measure the (ac) voltage between the Aux Pmp1 and the C terminals (4 and 6). • When the Aux Pump 1 LED is off, the reading should be 0 V (ac) and the pump should be off. • When the Aux Pump 1 LED is on, the reading should be 24 V (ac) + / – 10% and the pump should be running. 3.
