Outside sensor TA
The outside sensor (TA) of the control is
to be mounted at ca. 2.5 m height on the outside wall
of the building (north-west side). It is to be ensured that
the outside sensor is not directly affected by sun's
radiation or by wind, as this will adversely affect the
control behaviour. Do not place the sensor in the direct
vicinity of the evaporator either. Possible danger of
adverse influence on the control.
Sensors TQE and TQA
The flow and return sensors for the heating system
(WNA) are to be installed close to the switching box
inside unit. Sensor length 1.5m
Mixer sensor TMK
If a mixing circuit is installed in addition to the direct
heating circuit, a mixing valve sensor must also be
installed. The mixing valve sensor is supplied as a
contact sensor with band clamp and conductive paste.
The mixing valve sensor is to be mounted directly after
the mixer pump. If multi-layer or plastic pipework is
being used, a suitable metal bridge must be provided.
Hot water sensor TB
The hot water sensor is packed in the heat pump on
delivery. The sensor should be placed in the bottom
third of the tank, maximum in the middle. Ochsner hot
water tanks are fitted with corresponding sleeves for
the installation.
The current electromagnetic compatibility guidelines
are to be adhered to during laying.
The sensors are to be checked after wiring up.
- plausible values
- correct position
- sensors mixed up?
7.8 Pumps, drives 230 VAC
Pumps, (heating circuit pumps, hot water charge
pumps) as well as drives (mixing valves, etc.) are
connected directly to the control.
A test-run may only be undertaken on a fully-prepared
system that is ready for commissioning!
The hydraulics must be filled!
Danger of destroying the circulation pump!
A relay test can be carried out on the OTE control in
order to test the appropriate outputs (actuators).
The diverter modules from ESBE, which are delivered
by Ochsner, are not mixer motors, even when they
look similar.
7.9 Pumps, drives 400 VAC
3-phase pumps (heat source pump, charge pumps)
with higher ratings will not be directly connected to the
control. Power relays are provided in the distribution
box for this. See electrical circuit diagram Section 14.3
A separate circuit breaker is to be provided in the dis-
tribution box for the optional electrical auxiliary heater
in the hot water tank (Legionella protection). This func-
tion is optional and thus not in the heat pump's scope
of delivery.
A test-run may only be undertaken on a fully-prepared
system that is ready for commissioning!
