User Interface - Indicator LED
Power
• On when 115 V (ac) is applied.
Off when power disconnected or transformer fuse is blown.
Priority
• On when zone 1 has priority over zones 2 to 4.
RoomResponse
• On when modulating condensing boiler is operating below
maximum setting.
TM
Sequence of Operation
Zone Operation
When a thermostat calls for heat by closing the R and W terminals:
• 115 V (ac) is applied to the corresponding circulator pump.
• The corresponding zone indicator LED is turned on.
Boiler Operation
When a thermostat calls for heat by closing the R and W terminals:
• The boiler end switch XX is closed to fire the boiler.
The RoomResponseTM 0-10 V (dc) or 4-20 mA signal is sent
to a modulating-condensing boiler.
DHW Operation
Many modulating-condensing boilers have multiple temperature call inputs. Wire the DHW end switch to input recommended in the boiler's manual.
When a zone 1 calls for heat by closing the R and W terminals:
• The DHW end switch is closed to fire the boiler at the DHW
temperature.
• The Mod Boiler output is changed to 10 V (dc) or 20 mA.
Master / Member DIP Switch
Allows for unlimited expansion using additional Switching Relays and/or Zone Valve Controls.
The Master Switching Relay is wired and operates the boiler.
• If using a single Switching Relay set to Master.
When using multiple Switching Relays and/or Zone Valve
Controls, set one control to Master and set all other con­trols to Member.
T-Stat 1 Priority DIP Switch
When T-Stat 1 is calling for heat by closing the R and W terminals:
• 115 V (ac) is applied to the zone 1 circulator pump.
• Zone 1 indicator LED is turned on.
• Priority indicator LED is turned on.
• Zones 2 to 6 circulator pumps and LEDs are turned off.
• Expansion Member controls shut off their zones.
After 60 minutes of continuous zone 1 call for DHW heating, zones 2 to 6 and all Expansion Member control zones are able to turn back on. This prevents building freeze up if the DHW tank aquastat fails in the closed position.
Exercising DIP Switch
ON: Each circulator pump is energized for 30 seconds every 72 hours.
OFF: Circulator pump exercising disabled.
Zone 1
• On when thermostat 1 calls for heat.
Zones 2 to 4
• On when the corresponding thermostat calls for heat.
• Off during priority operation.
• Off when corresponding thermostat stops calling for heat.
Post Purge DIP Switch
ON: After the last thermostat stops calling for heat, the last circulator pump remains on for 2 minutes to purge heat from the boiler to the zone.
OFF: Post purge disabled.
Mod Boiler DIP Switch
Select either 0-10 V (dc) or 4-20 mA signal to the modulating condensing boiler. Consult the boiler manual to determine the signal type. The DIP switch position does not matter if the modulating boiler output is not used.
Fuses
• All fuses are T5A 250V slow blow.
• Fuses 1 to 4 correspond to the zone 1 to 4 circulator pump output. If a fuse is blown, first check that the pump is not seized and the wiring is not shorted. Then replace the fuse.
Fuse 7 and 8 correspond to the 24 V (ac) transformer power supply. If a fuse is blown, first check that the thermostat wiring is not shorted. Then replace the fuse.
Expansion Terminals
Connect the five wires of the expansion bus from the master to the member controls.

RoomResponseTM Signal
The RoomResponseTM signal adjusts the temperature of a modulating condensing boiler that accepts a 0-10 V(dc) or 4-20 mA input. It works by continually adjusting boiler water temperatures to the lowest possible value to meet comfort without wasting energy. This is done by monitoring each thermostat's on and off time pattern and determines the ideal water temperature for each zone. The control then chooses the highest water temperature requirement of all the thermostats and provides a 0-10 V (dc) or 4-20 mA signal proportional to the boiler operating temperature. The RoomResponse is a DOE compliant method of controlling boiler temperature to building load. The RoomResponse to on/off boilers.
Benefits of the RoomResponse
• Increase in boiler efficiency
• Reduction in room temperature swing
• Reduction in expansion noises from heating pipes

Limited Warranty and Product Return Procedure
Limite d Warranty The liability of tekmar under this warranty is limited. The
Purchaser, by taking rec eipt of any tekm ar product (“Product”), acknowl­edges the terms of the Limited Warranty in effect at the time of such Product sale and acknowledges that it has re ad and understands same.
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 from the documented date of installation if installed within twenty-four (24) months from the production date.
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 tekmar, and, without limiting the foregoing in any way, tekmar is not responsible, in contract, tort or strict prod­uct liability, for any other losses, c osts, expenses, inconveniences, or damages, whether direct, indirect, special, secondary, incidental or consequential, arising from ownership or use of the product, or from defects in workmanship or materials, including any liabilit y for fundamental breach of contract.
The pass-through Limited Warrant y applies only to those defective Products returned to tekmar during the warranty p eriod. This Limited Warranty does not cover the cost of the parts or labor to remove or transport the defective Product, or to reinstall the repaired or replacement Product, all such costs and expenses being subjec t to Purchaser’s agreement and warranty with its customers.
Any representations or warranties about the Products made by Purchaser to its cus­tomers which are different from or in excess of the tek mar 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 Warrant y 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 complianc e 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 c ompliance 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 NON-INFRINGEMENT OF ANY RELEVANT PATENTS OR TRADEMARKS, AND ITS COMPLIANCE WITH OR NON-VIOLATION OF ANY APPLICABLE ENVIRONMENTAL, HEALTH OR SAFETY LEGISLATION; THE TERM OF ANY OTHER WARRANTY NOT HEREBY CONTRACTUALLY EXCLUDED IS LIMITED SUCH THAT IT SHALL NOT EXTEND BEYOND TWENTY-FOUR (24) MONTHS FROM THE PRODUCTION DATE, TO THE EXTENT THAT SUCH LIMITATION IS ALLOWED BY THE GOVERNING LAW.
Product Warranty Return Procedure All Products that are believed to have 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.
