If any difficulties should arise during commissioning, you are asked not to undertake any unauthorized manipulations on the instrument. This will endanger your rights under the instrument warranty! Please contact your supplier or the main factory.

Introduction

Use

JUMO heat THERM-AT surface-mounting thermostats monitor and control temperatures in heat-generating plant and HVAC applications.
JUMO heat THERM-AT room thermostats control heating and cooling installations (climate control, ventilation) in commercial premises, nurseries, stables and HVAC applications.

Marking

Version in accordance with
EN 14597 as:
TR = Temperature controller
TW = Temperature monitor
STW = Safety temperature monitor
STB = Safety temperature limiter
Type examination to:
- EN 14597
- Pressure Equipment Directive (only STW and STB)
- UL 873 (in progress)
JUMO heat THERM-AT surface-mounting and room thermostats meet EN 60730 (VDE 0631).

Safety notes

Cutting through or kinking the capillary will lead to permanent instrument failure.
Liquid may escape in the event of a measuring system fracture.

Physical and toxicological properties of the expansion medium that may escape in the event of a measuring system fracture:

irritant| danger to health| toxic
< +200| no| +375| Class 1, mildly contaminant| no| no| no
≥ 200 ≤+350| No| +490| yes| yes| 1| no

At present, there is no restrictive statement from the health authorities concerning any danger to health over short periods and at low concentrations, e.g. after a fracture of the measuring system.

Mounting

General

Mounting position to DIN 16257,
NL 0 — NL 90

Mounting
Opening the housing

Opening the housing

Mounting the protection tube

The instruments must only be operated with the appropriate protection tubes.
For operation in air, without protection tube.

The temperature probe must be completely immersed in the medium being measured.

Probe-Ø	Prot. tube-Ø	Material
6 mm	8 x 0,75 mm	Brass / stainless steel

Wall mounting

Drilling jig, single thermostat
Drilling jig, dual thermostat
Bending radius ≥ 5 mm.
Shaped spring secures probe against sliding out

Pipe mounting

Shorten according to requirements.

Settings / functions

Setpoint adjustment TR
Control range limiting

Setpoint / limit setting TW/STW/STB

STB reset

The STB can be reset when the temperature has fallen about 10% below the preset limit.

STB reset

Response to measuring system fracture

If the measuring system is destroyed (i.e. the expansion liquid leaks) then the membrane pressure falls and the circuit will be permanently opened in the case of an STW or STB. On an STB, resetting is no longer possible.

Response to low temperature

If the probe temperature on an STB or STW falls below about -20°C, the circuit will open, but will automatically close again when the temperature rises.

IP54 protection

To achieve the enclosure protection rating IP54, the sealing elements must be inserted as shown in the diagram.

IP54 protection

Lead sealing

(not included in delivery)

Lead sealing

(1) Drill only in the cross-hatched area on both sides

Installation

Electrical connection

Regulations and notes

The electrical connection must only be made by qualified personnel.
The choice of cable, the installation and the electrical connection must conform to the requirements of VDE 0100 “Regulations for the installation of power circuits with nominal voltages below 1000 V”, or to the appropriate local regulations.
If contact with live parts is possible while working on the unit, it must be completely disconnected from the supply.
Earth the instrument at the PE terminal to the protective conductor. This cable must have a cross-section that is at least as large as the supply cables.

Electrical connection

contact (plug-in terminal) * suitable for conductor cross-section 0.75 — 2.5 mm2. Use core-end ferrule with stranded conductor.
Connection suitable for fixed cabling. Cable entry with strain relief. Attachment type X or M.
Implement the connection according to the wiring diagram.

Prepare the cables

(1) Use a suitable crimping tool

Make the connection

M ean ambient temperature effect, referred to setpoint| A deviation of the ambient temperature around the switching head or the capillary from the calibration temperature of +22′ C will cause a shift of the switching point.

Higher ambient temperature = lower switching point Lower ambient temperature= higher switching point

This effect can be minimized by using a temperature compensation depending on the instrument configuration.
