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.

Mixing Expansion Modules. The 345, Reset Module, and the
Mixing Expansion Modules can be located in the mechanical
room, while each Zone Manager can be remotely located
beside a manifold.

The 345 includes an auxiliary pump input (terminal 1) and
a powered auxiliary pump output (terminals 9 and 10).
When the auxiliary pump input is powered with 24 V (ac),
the auxiliary pump output is energized with 115 V (ac).
The auxiliary pump can be used in two different ways:
1) In single zone applications, a tN4 Thermostat or tN4
Setpoint Control activates the auxiliary pump output to
power the system pump.
2) In applications with Mixing Expansion Modules, the low
voltage system pump output on the Mixing Expansion
Module activates the auxiliary pump output to power the
system pump.

Limited Warranty The liability of tekmar under this warranty is limited.
The Purchaser, by taking receipt of any tekmar product (“Product”),

The tekmar Limited Warranty to the Purchaser on the Products sold hereunder is a manufacturer’s pass-through warranty which the Purchaser is
authorized to pass through to its customers. Under the Limited Warranty,
each tekmar Product is warranted against defects in workmanship and
materials if the Product is installed and used in compliance with tekmar’s
instructions, ordinary wear and tear excepted. The pass-through warranty
period is for a period of twenty-four (24) months from the production date
if the Product is not installed during that period, or twelve (12) months

The liability of tekmar under the Limited Warranty shall be limited to, at tekmar’s sole discretion: the cost of parts and labor provided by tekmar to repair
defects in materials and / or workmanship of the defective product; or to the
exchange of the defective product for a warranty replacement product; or
to the granting of credit limited to the original cost of the defective product,
and such repair, exchange or credit shall be the sole remedy available from

Any representations or warranties about the Products made by Purchaser to
its customers which are different from or in excess of the tekmar Limited Warranty are the Purchaser’s sole responsibility and obligation. Purchaser shall
indemnify and hold tekmar harmless from and against any and all claims,
liabilities and damages of any kind or nature which arise out of or are related
to any such representations or warranties by Purchaser to its customers.
The pass-through Limited Warranty does not apply if the returned Product
has been damaged by negligence by persons other than tekmar, accident,
fire, Act of God, abuse or misuse; or has been damaged by modifications,
alterations or attachments made subsequent to purchase which have not
been authorized by tekmar; or if the Product was not installed in compliance
with tekmar’s instructions and / or the local codes and ordinances; or if due to
defective installation of the Product; or if the Product was not used in compliance with tekmar’s instructions.
THIS WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS
OR IMPLIED, WHICH THE GOVERNING LAW ALLOWS PARTIES TO CONTRACTUALLY EXCLUDE, INCLUDING, WITHOUT LIMITATION, IMPLIED
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, DURABILITY OR DESCRIPTION OF THE PRODUCT, ITS

defects in workmanship or materials must be returned, together with a written description of the defect, to the tekmar Representative assigned to the
territory in which such Product is located. If tekmar receives an inquiry from
someone other than a tekmar Representative, including an inquiry from Purchaser (if not a tekmar Representative) or Purchaser’s customers, regarding
a potential warranty claim, tekmar’s sole obligation shall be to provide the
address and other contact information regarding the appropriate Representative.
