Anvendelse

Application

Termostat type RT 115 anvendes til styring

af tvungen ventilation i stalde og hønse-

huse.

The thermostat type RT 115 is designed

for control of forced ventilation in livestock

buildings and hencoops.

Fitting

Termostaten bevirker at der ventileres

uafbrudt sålænge rumtemperaturen er

højere end indstil-lingstemperaturen. Er

rumtemperaturen lavere, ventileres der

kun periodevis.

The thermostat has the eﬀect of constant

ventilation as long as the room tempera-

ture exceeds the temperature setting.

The thermostate should be ﬁtted in the

centre of the building, but in such a

position that the body heat from the larger

animals cannot directly inﬂuence the

thermostat.

If the room temperature is lower than the

temperature setting, there wil only be

intermittent ventilation. The cut-out period

is extended when the room temperature

falls, and if the temperature falls, and if

the room temperature is 2°C lower than

the temperature setting, the thermostat

cannot start the fan.

Udkoblingsperioden forlænges med

faldende rumtemperatur; og er rumtem-

peraturen 2°C lavere end indstil-lings-

temperaturen kan termostaten ikke starte

ventilatoren.

Setting

Set the thermostat by rotating the knob (5)

for a temperature which is approx. 1°C

higher than actually desired in the building.

RT 115´s specielle styreform skyldes den

ekstra føler (B) inden i termostathuset.

Langs føleren ligger et elvarmelegeme (C)

der kobles ind når ventilatoren kobles ud

og vice versa.

• If the fan then runs continuously, the

capacity of the fan is to low of the

outdoor temperature is too high

• If the fan runs intermittently, the

plant operation should not be iterfered

with until a stable room temperature is

reached. If the room temperature is then

too high or too low, resetting is done

• If the fan does not start, the room

temperature is too low to permit

ventilation.

The special kind of control oﬀered by

RT 115 is due to the extra sensor (B) inside

the thermostat housing. Alongside the

sensor there is an electric heater (C) which

is cut in when the fan is cut out, and vice

versa.

Montering

Et sæt Pg13,5 kabelforskruning er vedlagt

produktet i en separat pose. For at sikre

kapslingsgrad IP66 (enheder med automa-

tisk reset) eller IP54 (enheder med ekstern

RESET) er det nødvendigt at montere

Installation

A set of Pg13.5 cable gland is attached to

the RT in a separate bag. To ensure IP66

Danfoss RT 115 Manual: Questions and Answers

What does the extra sensor inside the Danfoss RT 115 do?

The extra sensor (B) inside the housing enables the special control method. An electric heater (C) alongside it activates when the fan cuts out, and deactivates when the fan runs. Installation Guide, p. 1

How do I install the Danfoss RT in my livestock building?

Mount the thermostat in the centre of the building where body heat from larger animals cannot directly affect it. A Pg13.5 cable gland is provided to maintain the IP66 or IP54 enclosure rating. Installation Guide, p. 1

What happens if the room temperature on a Danfoss RT 115 falls 2°C below the set point?

The thermostat cannot start the fan. The cut-out period lengthens as room temperature drops, allowing only intermittent ventilation until temperature rises closer to the setting. Installation Guide, p. 1
