Frequently Asked Questions - TH 16 Maico

What is the function of the Maico TH 16 thermostat?

The TH 16 is a thermostat that controls one or more fans based on air temperature. It activates the fans when the temperature exceeds the setpoint and deactivates them when it drops below.

What is the adjustable temperature range?

The setpoint temperature is adjustable from 0 to +50 °C using the rotary knob.

Can I use this thermostat outdoors?

No, the thermostat is exclusively designed for indoor use. Outdoor use may damage the device.

How to install the TH 16?

Installation must be carried out by a qualified electrician. Disconnect the power supply, fix the housing to the wall, connect the cables according to the wiring diagram (chapter 16 of the manual), then replace the cover and rotary knob.

What type of cable to use for connection?

The PG cable gland accepts cables with outer diameter of 6 to 12 mm. The terminals accept cross-sections up to 2.5 mm².

Can the thermostat control a three-phase fan?

Yes, but an additional contactor MAICO US 16 T (accessory) is required to switch three-phase fans.

What is the switching differential of the thermostat?

The switching differential (hysteresis) is 1.5 K. For example, if the setpoint is 30 °C, the fan turns on at 30 °C and turns off at 28.5 °C.

How to clean the thermostat?

Clean the housing and temperature sensor regularly with a dry cloth. Do not use aggressive cleaning agents.

What to do in case of malfunction?

Troubleshooting must be carried out exclusively by a qualified electrician. Refer to section 14 of the manual for procedures.

How to dispose of the thermostat at the end of its life?

Do not dispose of the device with household waste. Take it to a collection point for electrical and electronic waste to ensure environmentally friendly recycling.

1. General notes

These instructions contain important information. Follow the instructions given. Pass these instructions onto the owner. Keep these instructions somewhere safe.

The warnings provided indicate hazardous situations which, if not avoided, will result in death or serious injury in the case of DANGER or could result in death or serious injury in the case of WARNING. NOTICE indicates potential damage to the product or its surroundings.

2. Scope of delivery

Thermostat TH 16 incl. temperature sensor, these mounting instructions.

3. Specialist installer qualification

The thermostat may only be installed by a trained electrician, in line with these instructions. You are deemed competent if you can competently and safely connect units to an electrical power supply in accordance with a wiring diagram on the basis of your technical training and experience and are able to recognise and avoid risks and dangers associated with electricity.

4. Intended use

This thermostat is used for controlling fans depending on the air temperature. It is intended to be used indoors (greenhouses, machine or transformer rooms, stables etc.). Use additional MAICO US 16 T contactor (accessories) to switch three-phase current fans. The fans can be run in continuous or temperature-controlled operation with MAICO DS 10 rotary switch (accessories). The thermostat is only intended for domestic use and similar purposes.

5. Non-intended use

DANGER

Explosion hazard if operated in an explosive atmosphere in the case of ignition, e.g. from sparks.

Never use the thermostat in an explosive atmosphere.

NOTICE

Unit damage through modifications and alterations. Modifications and alterations to the unit are not permitted and release the manufacturer from any guarantee and liability.

NOTICE

Damage to the unit when used outdoors. Only use the thermostat in an indoor location.

6. Safety instructions

WARNING

Risks for people (including children) with reduced physical, sensory or mental capabilities or a lack of knowledge.

➢ Thermostat may only be installed, commissioned, cleaned and maintained by people who can safely recognise and avoid the risks associated with this work.

DANGER

Danger from electric shock. Before accessing the connection terminals:

▶ Switch off all supply circuits.
➢ Cover or block off neighbouring live components
Protect against being accidentally switched back on
➢ Check that there is in fact no voltage present.

7. Function/Operation

When the temperature exceeds/falls below the setpoint temperature, the thermostat switches one or more fans on/off.

The setpoint temperature can be set using the rotary knob [2].

The differential gap between the switch-on and switch-off temperature is 1.5 K.

11. Mounting

11.1 Mounting instructions

NOTICE

Incorrect measured values can result from unsuitable installation location. Locate the temperature sensor [7] correctly.

• Avoid disturbing influences.

• Avoid exposure to direct sunlight.
  Do not use in an area prone to draughts, hot or cold air, e.g. near stove, fridge, radiator, refrigerator, air intake, disk valve/internal grille, etc..
  Do not install in a unit with other heat-generating devices, e.g. a dimmer switch.

• Only install unit onto a dry, level surface. Any installation position can be selected.

• Only connect the unit to a permanently wired electrical installation after it has been completely mounted.
• The unit may only be operated using the voltage and frequency shown on the rating plate.
• Be sure to observe the relevant regulations for electrical installation; in Germany this is particularly VDE 0100, with the corresponding parts.
• Connection area for the PG screw connection [3] is suitable for connection cables with an external diameter of 6 to 12 mm.
• Connection terminals for cable with a max. cross section of 2.5 mm ^4 .
• A mains isolation device with contact openings of at least 3 mm at each pole is mandatory.
• The degree of protection is only guaranteed if installation is undertaken correctly and if the cables are correctly fed into the housing.

11.2 Unit mounting

1. Switch off power supply circuits, position a visible sign warning against being accidentally switched back on.
2. Pull the rotary knob [2] off.
3. Remove the cover [1] (4 screws).
4. Secure housing [6] to wall with 4 screws. Suitable mounting material is to be supplied by the customer.

NOTICE

Danger of short-circuits caused by damp if the connection cable is not inserted in the housing correctly.

➢ Ensure that the rubber seals on the PG screw connection tightly surround the cables.

1. Feed the connection cables into the housing through the PG screw connections. Secure the connection cables with the PG screw connection.
2. Connect up the connection cables as shown in the wiring diagram ( Chapter 16, page 12). Check the wiring and if necessary, tighten the screws in the connection terminals.
3. Remount the cover [1] (4 screws) and refit the rotary knob [2]. Make sure that the rotary knob shaft [5] is not damaged and that the rubber seal fits tightly round the shaft and housing edge.
4. Install the fan(s) in accordance with the operating instructions. Switch the mains fuse on.

12. Start-up

1. Check that the technical data has been adhered to rating plate.
2. Set the setpoint temperature using the rotary knob [2].
