Introduction

The following wiring brochure describes how to wire the tekmar Zone Manager 335. The 335 comes installed on the right

side of an enclosure with a blank plastic insert on the left. The blank insert may be replaced by a either a Reset Control

or an Expansion Module. The 335 allows for up to six tekmarNet

4 (tN4) thermostats, six 24 V (ac) zone valves and one

zone group pump. The wiring of tekmarNet

4 (tN4) components is simple and cost effective.

Electrical Drawings The electrical drawing examples on the following pages show the 335 in common applications. These drawings have a brief explanation of what is being operated in each system. Choose the components in your system and use the drawings as a guide to aid in wiring your system. These are only concept drawings, not engineered drawings. They are not intended to describe a complete system nor any particular system.

Wiring the Control Terminals 1-43 • Strip all wiring to a length of 3/8 in. or 10 mm for all terminals. • Refer to the current and voltage ratings at the back of this brochure before connecting devices to this control. This section explains how to wire individual devices to the Zone Manager 335. For step by step wiring refer to the terminal number on the right of the page. • Before wiring ensure all power is turned off and take all necessary precautions.

Wiring the Input Power Terminals 28-29 Provide a 15 Amp circuit for the power input. Wire 115 V (ac) power to terminals 28 and 29. • Connect 115 V hot (L) to terminal 28. • Connect 115 V neutral (N) to terminal 29. • Connect the ground wire to one of the ground screws provided in the wiring chamber.

Adding Extra VA Wiring an External Transformer Terminal 25 Use the supplied Job Records to determine if an external 24 V (ac) transformer is required. 4. For each of the selected zones, connect the thermostat’s R wire to the external transformer’s 24 V (ac) R output. (Do not use the 335’s R terminals) If the combined total 24 V (ac) load exceeds 50 VA, an external NEC / CEC Class 2 transformer is required. 5.

Troubleshooting the Control General The following tests are to be performed using standard testing practices and procedures and should only be carried out by properly trained and experienced persons. Test Meter ### Control Terminals A good quality electrical test meter, capable of reading from at least 0-300 V (ac), 0-30 V (dc), 0-2,000,000 Ohms, and testing for continuity is essential to properly test the wiring and sensors.
PAGE 11
Testing the Input Power Terminals 28, 29 1. Remove the front cover from the control. 4. If power is present but the ‘Power’ LED is lit amber: 2. Use an electrical test meter to measure (ac) voltage between the Input Power L and N terminals (28 and 29). The reading should be 115 V (ac) + / – 10% and the ‘Power’ LED should be lit green. • Check the field replaceable transformer fuse on the Zone Manager. • If the fuse is blown, determine the cause of the failure before replacing the fuse. 3.
