General description

The TCY-MT-U is a stand-alone electronic temperature controller with one control
loop. It may use up to 2 PI-sequences. The TCY-MT-U features one internal NTC
temperature sensor, up to two external sensor inputs and up to two analog outputs.
The configuration has been reduced to a minimum to allow for simple and off-the­shelve usage. For more advanced features and current inputs and outputs the TCI
product range is recommended. The TCY-MT-U can be configured using the
standard operation terminal. No special tool or software is required.

Selection of actuators and sensors

Temperature sensors:

Use only our approved NTC sensors to achieve maximum accuracy. Recommended is SDB-Tn10-20 as Duct sensor, SRA­Tn10 as Room sensor and SDB-Tn10-20 with AMI-S10 as immersion sensor.

Modulating actuators:

Choose actuators with an input signal type of 0–10V DC or 2–10V DC.

Installation and safety advice

Caution! This device is intended to be used for comfort applications. Where a device failure endangers human life and/or

property, it is the responsibility of the owner, designer and installer to add additional safety devices to prevent or detect a
system failure caused by such a device failure. Vector Controls or its affiliates cannot be held liable for any damage
caused by such a failure. Failure to follow specifications and local regulations may endanger life, cause equipment damage
and void warranty.

Installation

The unit consists of two parts: (a) The power case with attached mounting plate and (b) the front part.

Mounting location

 On an easy accessible interior wall, approx. 1.5 m (4.5’) above the floor in an area of average temperature.
 Avoid exposure to direct sunlight or other heat sources, e.g. the area above radiators and heat emitting electrical

equipment.

 Avoid locations behind doors, outside walls and below or above air discharge grills and diffusers.
 Location of mounting is less critical if external temperature sensors are used

Installation

1. Connect the wires to be connected to the terminals of the power case according to wiring diagram

2. Install the mounting plate to the flush mounting box. Make sure that the nipple with the front holding screw is

facing to the ground. Make sure the mounting screw heads do not stand out more than 5 mm (0.2”) off the
surface of the mounting plate.

3. Ensure that the jumpers are set correctly.

4. Slide the two latches located on the top of the front part into the hooks at the upper side of the mounting plate.

5. Carefully lower the front part until the interconnector reaches the mounting-plate. Continue pressing in a gentle

way until the front part is fully connected. While inserting the connectors, a slight resistance can be felt. This is
normal. Do not use excessive force!

6. With a Philips-type screw driver of size #2, carefully tighten the front holding screw to secure the front part to

the mounting plate. This screw is located on the front lower side of the unit. There is no need to tighten the
screw too much.
