Installation
CAUTION
Improper installation and operation of this control could result in damage to the equipment and possibly even personal injury. It is
your responsibility to ensure that this control is safely installed according to all applicable codes and standards. This electronic
control is not intended for use as a primary limit control. Other controls that are intended and certified as safety limits must be placed
into the control circuit.
STEP ONE
GETTING READY
Check the contents of this package. If any of the contents listed are missing or damaged, please contact your wholesaler or tekmar
sales representative for assistance.
Type 361 includes: One Mixing Control 361, One Outdoor Sensor 070, Two Universal Sensors 0
82, Data Brochures D 361,
D 070, D 001, Application Brochure A 361, Essay E 021.
Note: Carefully read the details of the Sequence of Operation to ensure that you have chosen the proper control for your application.
STEP TWO
MOUNTING THE BASE
Remove the control from its base by pressing down on the release clip in the wiring chamber and sliding the control away from it. The
base is then mounted in accordance with the instructions in the Data Brochure D 001.
STEP THREE
ROUGH-IN WIRING
All electrical wiring terminates in the control base wiring chamber. The base has standard 7/8” (22 mm) knockouts which accept
common wiring hardware and conduit fittings. Before removing the knockouts, check the wiring diagram and select those sections of
the chamber with common voltages. Do not allow the wiring to cross between sections, as the wires will interfere with safety dividers
which should be installed at a later time.
Power must not be applied to any of the wires during the rough-in wiring stage.
• Install the Outdoor Sensor 070, Boiler Sensor 0
82, and Mixing Sensor 082 according to the instructions in the Data Brochure D 070,
and run the wiring back to the control.
• If an Indoor Sensor 076 or 077 is used, install the indoor sensor according to the instructions in the Data Brochure D 074, and run
the wiring back to the control.
• Run wire from other system components (pump, boiler, etc.) to the control.
• Run wires from the 120 V (ac) power to the control. Use a clean power source to ensure proper operation. Multi-strand 16 AWG
wire is recommended for all 120 V (ac) wiring due to its superior flexibility and ease of installation into the terminals.
STEP FOUR
ELECTRICAL CONNECTIONS TO THE CONTROL
The installer should test to confirm that no voltage is present at any of the wires. Push the control into the base and slide it down until
it snaps firmly into place.
Powered Input Connections
120 V (ac) Power
Connect the 120 V (ac) power supply to the Power L and Power N terminals (3 and
4). This connection provides power to the microprocessor and display of the control.
As well, this connection provides power to the
Sys Pmp terminal (5) and to the Var
Pmp terminal (7) from the Power L terminal (3).
Mixing Demand
To generate a mixing demand, a voltage between 24 V (ac) and 240 V (ac) must be
applied across the
Mixing Demand terminals (1 and 2).
