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.

tekmarNet ® 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).
