General

Benchmark places responsibilities on both manufacturers and installers. The purpose is toensure that customers are provided with the correct equipment for their needs, that it is installed,commissioned and serviced in accordance with the manufacturers instructions by competentpersons and that it meets the requirements of the appropriate Building Regulations. The BenchmaChecklist can be used to demonstrate compliance with Building Regulations and should be provideto the customer for future reference.Installers are required to carry out installation, commissioning and servicing work in accordance withe Benchmark Code of Practice which is available from the Heating and Hot water Industry Counc

who manage and promote the Scheme.Visit www.central heating.co.uk for more information.

General

The outdoor sensorenables weathercompensation by providing an advanced

level of modulation, achieving an additionlevel of efciency. This control compensafor the outside temperature by modulatinthe lower radiator temperatures in warmeweather and higher radiator temperaturescolder weather.

The outdoor temperature compensation ieasily congured using either the boilersinterface controls or the interface of anexternal Glow-worm Climastat or Climaprroom control (if tted). Optimum comfortand efciency is achieved when used inconjunction with a Climastat or Climapro(in modulating mode). The outdoor senso

can also be used with a conventional on/thermostat.

General Information


4/24


The installation and the commissioning ofthe Outdoor sensor has to be carried out bya competent person in accordance with the

current regulations.The maintenance and the repairing of theOutdoor sensor will also require the use of acompetent person.

Documents

Please keep these instructions as well as anydocuments enclosed, for future reference.

We accept no liability in case of damage dueto the non-compliance of these instructions.

General Information

Application

WARNING:Isolate the boiler from theelectrical supply. A competant personshould make the electrical connections.

Use a cable that complies with thespecications given in Technical data, page7. Route the cable from the outdoor sensorto the boiler electrical cartridge at the boiler,refer to the literature supplied with yourboiler for location and access.

Refer to diagram 5, thread the cable through

the electrical sealing gland. Connect thecable to the electrical connection, polarityis not important. Fit the sealing gland, thissecures the cable and gives a water tightseal. Connect the cable to OTC1 and OTC2connection in the electrical cartridge atthe boiler, polarity is not important, refer todiagram 6.

Note:Ultracom hxi & Flexicom hx open ventsystem models only. The edge connector willneed to be tted, see diagram 7.

Choosing and Setting SensorHeating Curve.

A gradient must be chosen from the range

shown on page 17, labelled 0-9.

The decision as to which heating curveshould be used is based on two factors:

1. The average minimum outside

temperature of the region.

2. The maximum temperature which the

heating appliance can provide.

NOTE: Consider the level of heat loss in

comparison to typical UK heat loss e.g.

(double glazing, loft insulation and cavity wall

insulation).

Method with example.

The following example describes theprocess. The temperatures quoted should

be substituted with real values to nd therequired heating curve.

1. Select the average minimum outdoor

temperature expected in your region where

the sensor will be installed. For example at

the peak of winter the temperature may dropto -5C. This would be the value selected

from the Outdoor temperature C axis.

2. Select the maximum output temperature

of the heating appliance from the Heating

ow temperature (C) axis. For example this

could be 82C.

Adjusting room temperature setpoint.

By default the outdoor sensor aims to provide

a room ambient temperature of 20C. Insome situations it may be necessary to have

a lower or higher ambient room temperature

the adjustment is made in terms of an offset

value, which is entered into the appliance via

diagnostic menu d.46. Refer to the

following diagrams and text to do this.


Running screen is displayed

Press and hold the mode button. When

the screen is lit orange and displays 0,

If extra heating comfort is required, the roomtemperature setpoint can be increased viadiagnostic menu d.46. D.46 provides a

means to offset from the default 20C roomset point. For example to increase the targetroom temperature to 22C set d.46 to thevalue 2.

Range of value d.46: -10 to 10.


For example:

10C = offset -10

20C = offset 0

30C = offset 10

Making Adjustment on Climastat

Refer to your Climastat instructions, section6 Commissioning. The heating curve is

adjusted via Menu 2. Acess to this menuis achieved by following the steps stated inAdjustments.

Making Adjustment onClimapro/ Climapro RF

Refer to your Climapro/Climapro RF

Commissioning Instructions. The heating

curve is adjusted via menu COMP which is

accessible by procedure stated in the table in

the Commissioning section.

Glow-worm Climapro or Climastat controls

Adjusting Room Ambient

With the heating curve correctly setup foryour specic region, the room temperature

can be adjusted. This is achieved byincreasing or decreasing the setpointtemperature of your Climastat or Climapro/Climapro RF roomstat.

For systems with a Glow-worm Climapro.To adjust the room ambient set pointtemperature, refer to sections, Setting the

Comfort temperature or Central heatingtemporary override - central heating of theClimapro instructions for use, installation andservicing literature.

For systems with a Glow-worm Climastat.To adjust the room ambient set pointtemperature, refer to section 2 instructions

for use of the Climapro instructions for use,installation and servicing literature.
