Installation

3 Installation

3.1 Choosing the right installation position

3.1.1 Installation in the reference room

If the system is operated in room temperature-dependent mode, observe the following requirements:

• Installation position on an internal wall (Æ fig. 1)

• Maintain the specified distance from the door (to avoid draughts).

• Allow clearance below the programming unit (Æ fig. 1, shaded area) to ensure correct temperature measurement.

• The reference room (= installation room) must be as representative as possible of the entire home. External heat sources in the reference room (e.g. sunlight or other heat sources such as an open fire) affect the control functions. This means it may be too cold in rooms without external heat sources.

• Always open the thermostatic radiator valves fully in the reference room to prevent the two temperature controllers influencing each other.

Fig. 1 Minimum clearances for installation in a reference room

If there is no suitable reference room, we recommend setting the system to weathercompensated control instead (this requires an outside temperature sensor). Alternatively, you could install an external room temperature sensor in the room with the greatest heat demand (e.g. living room).

Installation

Logamatic EMS – 6 720 801 387 (2011/05)

3.1.2 Installation on boiler

Installation directly on the boiler is possible where the boiler is equipped with the Energy Management System (EMS).

The outside temperature sensor for weather-compensated control is not delivered as standard, but can be ordered as an accessory.

3.2 Types of installation

The programming unit can be installed in three different ways:

• As the only programming unit in the system (basic setting): the programming unit is installed in a living room (reference room) or on the boiler

Example: single family house with one heating circuit.

• As the only programming unit in a heating system with two or more heating circuits

(Æ fig. 2, [1]). Examples: underfloor heating on one storey, radiators in the others, or a home combined with a separate dwelling unit or with a medical practice room.

• In association with a remote programmer (e.g.RC2x, RC20/RF, fig. 2, [2]) In this case there are always two separate heating circuits. Remote control units cannot be used for boilers with UBA1.x. Examples: underfloor heating on one floor, radiators on the others; or a main flat together with a separate granny flat or doctor's surgery.

If a HM10 hybrid module is used, the installation must be carried out with the wall bracket. If it is installed on the boiler, it does not function correctly.

1) Not possible if the HM10 hybrid module is used

2) Not possible with boilers with UBA1.x and DBA.

Installation

Fig. 2 Options for a heating system with two heating circuits

1 Both heating circuits are controlled by one programming unit. 2 Each heating circuit has its own programming unit / remote control unit.

3.3 Installation and connections

The wall bracket can be attached directly to the wall or on a flush-mounting box.

When mounting on a flush box, note the following:

B Draught from within the flush box must not be able to falsify the capture of the room temperature

by the programming unit. If required, stuff the flush box with insulation material.

B Use horizontal or vertical fixing holes [4]. B Fit the wall mounting base (Æ fig. 3, left). B Connect a two-core BUS cable from the Energy Management System (EMS) to the “RC” cable

terminals [5]. – Cable type: 2 x 0.75 mm

(0.5 – 1.5 mm2), max. length 100 m

– Polarity is irrelevant for the two wires.

B Do not lay the cables parallel to power cables.

Only use the wall mounting base with screw terminals. B Replace wall mounting bases without screw terminals that may already be installed.

5.7 Operating information

Subscribers on the EMS-BUS

In a BUS system, only one subscriber can carry out the calculations for a heating circuit. Consequently, only one RC35 programming unit may be installed in each heating system. If additional programming units (e.g. RC2x) are required, they must be installed as remote programmer

with a set heating circuit address (Æ page 31).

Thermostatic radiator valves in the reference room

Thermostat valves on the radiators in the reference room2) are not required with room temperature compensated control. Fully open any thermostatic radiator valves in the reference room.

Anti-block protection

In all operating modes all heating pumps are switched on for 10 seconds and then switched off again each Wednesday at 12:00 o'clock, in order to prevent damage to the pumps. The mixers are then set to "OPEN" for 10 seconds and then "CLOSED". All pumps and mixers then return to their normal, regulated operation.

6.1.1 Building type (adjusting the outside temperature)

A building's heat storage capacity and its characteristic resistance to heat transfer will delay the effect of outside temperature fluctuations on the rooms inside. Consequently, it is not the current outside temperature that is crucial but the so-called adjusted outside temperature. Parameter building type enables the adjustment to be applied that takes account of the fluctuating outside temperatures. This enables the control to be matched to the characteristics of the building.

The control unit calculates the time constant for adjusting the outside temperature, using the factor given in Tab. 11 for the stated building type and an internal multiplier, the "runtime" (= 6 minutes). The time constant is the product of: factor x runtime = adjustment time constant in hours.

Should the adjusting of the outside temperature be switched off?

This function is not available with boilers with UBA1.x and DBA.

Example: heating system with heating circuit 1 and heating circuit 2 (Æ page 12)

6.4.2 Control mode (outside temperature compensated/room influence)

In the Logamatic control unit the heating curve specifies the temperature of the heating water in the boiler. It can be selected whether this heating curve is influenced solely by the outside temperature, or whether a mix from the characteristics of the outside temperature and the room temperature define the heating curve.

• Outside temperature compensated: with this setting a boiler temperature, which is calculated in the control unit, is controlled by means of a change in the adjusted outside temperature combined with selected settings for room target value, offset, design temperature and minimum outside temperature. This temperature is then delivered to the radiators or underfloor heating system by means of permanent operation of the heating circuit pump. The only circumstances in which this setting can result in the heating circuit pump being switched off are summer mode, night setback (subject to the selected setback mode) or DHW mode (only with DHW priority).

• Outside temperature compensated with the influence of room temperature (basic setting): this type of control works exactly as the pure weather compensated control, but with the difference that, by means of the parameters for maximum room influence, it can be defined whether, and to what degree, the room temperature has an influence on the heating curve. The programming unit/remote control must be installed in a reference room to ensure that a representative room temperature is captured. The larger the parameter is set, the larger is the proportion of the room temperature on the design formation of the heating curve (basic setting 0 Kelvin) This applies when the room temperature exceeds or falls below the set room temperature. If the maximum room influence parameter is set to 0, the heating characteristics will be controlled solely by outside temperature.

6.4.3 Heating curve

Parameter: design temperature, maximum and minimum flow temperature and room temperature offset (parallel shift).

The heating curve is the decisive basic factor for an economic and convenient operation of the heating system with outside temperature compensated control. For the calculation of this curve the Logamatic control system requires information about some of the heating system characteristics, and from this it calculates automatically and by means of a mathematical formula the optimum heating curve. As part of this it takes into account the adjusted outside temperature and the room control temperature. The room control temperature is in turn an internal calculation factor, which is comprised of the desired room temperature (room target temperature) and the room influence. By means of this the user can immediately influence the heating curve by changing the room target temperature. The heating curve (Æ display 7, page 37) is essentially defined by its base point and end point. The base point is located at 20 °C flow temperature at a room temperature of 20 °C with an adjusted outside temperature of 20 °C. The end point of the heating curve must be set according to the design temperature of the heating system. The defining factors for the run of heating curve (incline/steepness) are the two parameters minimum outside temperature (the lowest expected outside temperature in a region, page 28) and the design temperature (the flow temperature which should be reached at the minimum outside temperature), Æ display 7, left.

With the parameter for minimum flow temperature a minimum target value can be specified (Æ display 7, [4], page 37). The burner starts again if the set value is no longer achieved.

The heating characteristic curve can be shifted up or down parallel to the original curve by adjusting the room temperature offset parameter and/or the set room temperature (Æ fig. 7, right, page 37). Setting the offset may be advisable should the room temperature measured by a thermometer deviate from the selected set value.

The X axis of the heating curve depicted graphically in the display relates to the area of +20 °C to – 20 °C. Under design parameter the minimum outside temperature, which is set under system data, is depicted by a circle. If a minimum outside temperature of under – 20 °C is entered, the depiction is however no longer completely correct (the circle no longer lies on the heating curve).

6.4.4 Reduction modes (night reduction)

There are a number of different setback modes available, which allow night setback to be adjusted to suit the differing needs of the user:

• Reduced operation: the rooms are maintained at a reasonable temperature at night by constant heating operation (pump runs constantly). A set room temperature for nighttime can be set. It is at least 1 K lower than the set day temperature. The heating curve is calculated in accordance with these details. We recommend these settings for an underfloor heating system.

• Shutdown operation: boiler and heating circuit pump are off, frost protection is active. The pump only starts in frost protection mode. This setting is not recommended if there is a risk that the building would cool down too severely.

System settings (Service menu – Settings)

Logamatic EMS – 6 720 801 387 (2011/05)

• Room setback mode: The heating system operates as if in setback mode (as described under “reduced operation”), if the room temperature falls below the selected night temperature (set value). Boiler and heating circuit pump stop (as described under setback mode “shutdown operation”) if the room temperature exceeds the set night temperature by more than 1 K. This setback mode is only possible if a programming unit/remote control is installed in a representative room (reference room) or if the room temperature is captured by an external room temperature sensor.

• Outdoor compensation mode: if the adjusted outside temperature falls below the value of a settable outside temperature threshold, the heating system works as in the reduced heating mode (as described under “reduced mode).” The heating system remains off above this threshold (as described under setback mode “shutdown operation”). This setback mode is suitable for heating circuits which do not have their own programming unit / remote control unit. The operating mode protects the rooms from cooling down too much once a certain outside temperature is reached.

6.4.5 Frost prot.

The frost protection function offers the following options:

• No frost protection (frost protection is switched off).

• Outside temperature(outside temperature sensor required)If the outside temperature falls below the threshold of the settable frost limit temperature, the heating circuit pump is automatically switched on.

• Room temperature(Room temperature sensor of the RC35 or RC2x). If the room temperature falls below the fixed set value of 5 °C, the heating circuit pump is automatically switched on. The heating circuit pump stops automatically if the room temperature rises above 7 °C.

CAUTION: System damage through frost! The settings no frost protection and room temperature provide either no frost protection or inadequate frost protection. When these settings are selected, the display shows a message indicating the risk of freezing.

B For reliable frost protection, use the outside temperature setting.

The setting room temperature offers no absolute frost protection, as lines routed through external walls may freeze up, for example, although the temperature in the reference room may be significantly above 5 °C.

From which outside temperature should the reduction be interrupted?

DIN-EN 12831 requires that, for the maintaining of a comfortable heat, all heating surfaces and heat generators are designed to a defined output, if the heating system cools down below a defined value due to night reduction.

In the parameter From which outside temperature should the reduction be interrupted? it is possible to set an outside temperature threshold (related to the adjusted outside temperature, (Æ page 27).

Fig. 8 shows how the frost protection function works, with and without this parameter activated. Settings selected: frost protection by outside temperature; frost protection temp. 5°C.

of the following types: locking, blocking or plant error.

• Locking errors

When the fault is eliminated, the heating system must be manually unlocked.

For this, press Reset on the boiler.

• Blocking errors

: with blocking faults the heating system continues to work automatically as

soon as the error status is lifted.

• System errors in the heating system are recorded in the RC35 programming unit, with the

exception of faults in the boiler or burner, which are either “locking” or “blocking” faults. The heating system keeps operating as much as possible during the fault; a reset is not required.
