General

The 334 can connect to four tekmarNet

2 (tN2) Thermostats.

When a thermostat calls for heat, the 334 turns on the

corresponding zone output which can either provide power

to a zone pump or a zone valve. Zone 4 can be connected

to a Heat – Cool thermostat. When the thermostat is

operating the cooling system, the 334 turns on the cooling

relay. When the thermostat is operating the fan, the 334

operates the fan relay.

The 334 includes two wiring plugs. The top plug provides

tN4 communication and 24 V (ac) to the left hand module.

When the top plug is installed to an outdoor reset module,

the 334 is connected to bus 1. The bottom plug provides

120 V (ac) power.

Zone Group Pump

Each zone has a corresponding Zone Group Pump DIP

switch.

Zone Group Pump DIP switch set to On:

The Zone Group Pump turns on when the zone calls

for heat.

Zone Group Pump DIP switch set to Off:

The Zone Group Pump does not turn on when the zone

calls for heat.

•

Zone Group Pump Delay

Each zone has a corresponding Zone Group Pump Delay

DIP switch.

Note: The Zone Group Pump Delay only operates if the

Zone Group Pump DIP switch is set to On.

Zone Group Pump Delay DIP switch set to On:

The Zone Group Pump turns on 3 minutes after the zone

calls for heat.

The Zone Group Pump turns off 15 seconds after the

zone stops calling for heat.

Zone Group Pump Delay DIP switch set to Off:

The Zone Group Pump turns on when the zone calls

for heat.

The Zone Group Pump turns off when the zone stops

calling for heat.

2 Operation

The 334 uses tekmarNet

2 (tN2)

communication to connect to tN2

compatible thermostats. The 334

in turn translates the information to

tekmarNet

4 (tN4) communication.

The tN2 thermostats appear on the

tN4 communication bus in the same

manner as tN4 thermostats.

Important Note:

The 334 is NOT compatible with previous

generation tN2 products such as the

Remote Display Module 040 or the

Start / Stop Module 039.

tekmarNet

4 Expansion

The 334 has four wiring terminals to allow for tN4 expansion

to other tN4 devices. The tN4 expansion can be used to

connect the 334 to other Zone Managers or Zone Expansion

Modules to add extra heating zones. The tN4 expansion

can also be wired to a Mixing Expansion Module. This

option requires the use of a tN4 Outdoor Reset Control to

operate the mixed water temperature. The tN4 expansion

also allows the installation of a tN4 Timer 033, a single tN4

Thermostat or a single tN4 Setpoint Control. The powered

zone group pump is activated by the Mixing Expansion

Module, Thermostat, or Setpoint Control whenever the

pump input (terminal 4) is powered with 24 V (ac).
