Danfoss ECtemp 316
3Installation Guide
1 Introduction
ECtemp 316 is an electronic thermostat to be installed in
electric cabinets with DIN rail attachment. The thermostat
must be installed via an all-pole disconnection switch.
ECtemp 316 applies to the control of room temperature,
oor temperature, ventilation, cooling or to the control of
snow melting in gutters and similar installations.
For measuring purposes either a wire sensor or an external
air sensor is used.

The thermostat has a button to adjust the temperature
setting with a scale from -10 °C to +50 °C . An LED indicator
shows standby periods (green light) and heating periods
(red light).

1�2 Safety Instructions
Make sure the mains supply to the thermostat is turned o
before installation.
IMPORTANT: When the thermostat is used to control a
oor heating element in connection with a wooden oor or
similar material, always use a oor sensor and never set the
maximum oor temperature to more than 35 °C.

Installation Guide6
Please also note the following:
• The installation of the thermostat must be done by an
authorized and qualied installer according to local
regulations.
• The thermostat must be connected to a power supply
via an all-pole disconnection switch.
• Always connect the thermostat to continuous power
supply.
• Do not expose the thermostat to moisture, water, dust,
and excessive heat.
2 Mounting Instructions
Please observe the following placement guidelines:
• Install the thermostat in an electric cabinet with DIN
rail attachment or a separate DIN attachment accord-
ing to local regulation on IP classes.
• Do not place the thermostat in a way that it will be
exposed to direct sunlight.

The screen of the heating cable must be connected
to the earth conductor of the power supply cable by
using a separate connector.
Note: When you use the wire sensor for oor heating,
always install the sensor in a conduit.
3. Turn on the power supply.
Protective separation
The thermostat is designed so that the sensor circuit is gal-
vanically separated from the high voltage part which means
that the sensor part is regarded as a low voltage part.

C Hysteresis
3�1 Hysteresis
When the thermostat is used to apply with either heat-
ing systems or refrigerating systems, and the requested
temperature is between -10 °C to +50 °C, then it is recom-
mendable also to adjust the hysteresis Caccording to the
requested regulating range.
As an example if the temperature is set at 18 °C and the hyster-
esis at 3 °C the thermostat will switch on at 18 °C and o at 21 °C.
For controlling of room temperature the Hysteresis is rec-
ommended to the set point of 1 °C.
3�2 Minimum Temperature Limiter
When the thermostat is used in connection with snow and
ice melting systems, it is recommendable also to use and
adjust the minimum temperature limiter (B) which ensures
Danfoss ECtemp 316
9Installation Guide
both an upper and lower temperature range in between
which the thermostat allows the system to heat.
The requested maximum temperature range has to be
between -10 °C to +50 °C and the requested minimum
temperature range has to be between -10 °C to +5 °C.
An link between terminal 9+10 must be connected to acti-
vate the use of the minimum temperature feature when the
thermostat controls snow and ice melting in gutters, valley
gutters and down pipes, where the waste of unnecessary
energy must be avoided. In particular by extremely cold
weather where owing water or moisture does not occur.
When the temperature drops below the minimum tem-
perature set value, the thermostat stops heating and the
LED indicator turns yellow.
When the temperature exceeds the maximum temperature
setting, the thermostat stops heating and both the indica-
tor for minimum and maximum temperature disappears.
3�3 Temperature Set-back
By connecting an external timer to terminals 4 and 6, the
thermostat can be set to reduce the temperature by 0 °C to
8 °C (A).
