Horstmann, advanced simplicity
Control, it's what we're good at and in domestic central heating and hot water installations that means more accurate control of time and temperature all around the system.
Sometimes the solution needs to be simple, like a room stat and timer installation or it can be more sophisticated requiring 3 or 4 channel electronic programmers which can independently handle hot water and separate heating zones.
Our latest electronic room thermostats are clever too. Their latest thermostat technology is proven to save up to 10% in energy costs* by increasing the efficiency of the boiler firing regime.
Wireless, mains or battery versions of our controls are available across the Horstmann range. Well worth checking out.
Horstmann... Together, we're in control.

ServicePlus Series 2 Service Interval Programmers ServicePlus is a range of programmers and time switches developed to facilitate compliance with the Gas Safety (installation and Use) Regulations 1998. Although not intended to replace the normal servicing regime, ServicePlus can act as a supplementary reminder to enabling compliance. Features an upgraded back lit display screen and incorporates an automatic GMT/BST clock. Ÿ Service interval safety check clock Ÿ Can fully or partially shut down the system once a service period is overdue Ÿ Service period is set by installer using unique key code Ÿ Facilitates compliance with Gas Safety Regulation 36 Ÿ Building Regs Part L compliant
21
Specification The ServicePlus service interval timer range is based on the popular Centaurplus range of domestic central heating programmers and timeswitches. All the functions and facilities available in the CentaurPlus range are also available in the equivalent ServicePlus model. E.G. S27R is based on C27, S17R is based on C17 etc. The ServicePlus range of programmers and time switches are designed to carry out a full or partial boiler shutdown once the servicing date has become overdue. The Installer can set the ServicePlus so that either a full shutdown will occur after a 28 day warning period of the boiler service becoming due or partial shutdown can be selected where a 15 minute period of heating and hot water will occur every hour. These 15 minute periods will occur every hour but never consecutively from one hour to the next. If programmed on installation, the 15 minute 'On' periods will reduce the effectiveness of the heating system so that it becomes uncomfortable for the occupier without it providing no heating at all. This should have the effect of encouraging the householder to call the service engineer to check the system.

HRT4-A, HFT4 and HTT4 Mains Operated Electronic Room Thermostats This range of purpose designed room thermostats from Horstmann offer the latest energy saving control technology combined with established Horstmann design and manufacturing expertise. This makes them suitable for use in most types of heating system that respond to a 230 volt mains electrical On/Off signal. They are also perfect partners for use with Horstmann Programmers and Zone valves. Ÿ 230 volt mains operation Ÿ TPI temperature control software Ÿ Standard, Frost and Tamperproof versions Ÿ Easy to install and use
Designed to look good, these thermostats will out perform many older styles of thermostat and can often produce savings in the order of 10% over and above those achieved by traditional units using older technology. The temperature control accuracy of +/- 0.5°C and different TPI settings – for Gas, Oil and Electric systems – will reduce the temperature swing that normally occurs with older style thermostats. As a consequence these thermostats will help to save energy as the control algorithm allows the boiler to operate in condensing mode for longer periods.

TPI energy saving software
where it is used – the benefits Time Proportional Integral (TPI) energy saving software is key to the performance of thermostats in a number of Horstmann's central heating controls – notably the HRT range of room thermostats, C-Stat programmable room thermostats, the CentaurPlus ZW combined wireless room 'stat and time-switch and the ThermoPlus range of easy-to-use programmable room thermostats. TPI has proven energy saving features that have been independently assessed (by TACMA) to save the householder up to 10% annually on fuel costs. So, how does it work? Traditionally, room stats use either mechanical bellows or thermally operated switches. These are much less accurate in maintaining the room temperature at the 'set point' as they produce fairly large swings of temperature caused by the differential between the on and off switch point. In turn, this causes the boiler to fire inefficiently and often over-heat the room. A thermostat controlled by TPI software makes a series of precise calculations once it has entered the control or proportional band. When set to 6 cycles per hour the software will calculate the amount of heat needed during each 10 minute period and switch the boiler on for a proportion of that 10 minutes to maintain the set temperature. This stops the wide fluctuations in temperature that can occur with conventional thermostats. The TPI software then 'fine tunes' the calculations to constantly review performance and carry out further, fine, adjustments if necessary. When used with a condensing boiler, the TPI thermostat will help to save energy as the control algorithm allows the boiler to operate in condensing mode more consistently compared to older types of thermostat. This effect is achieved by keeping the return water temperature below the critical 56ºC needed for the boiler to operate in condensing mode for longer.

Optimum start
C-Stat programmable room thermostat The Horstmann C-Stat is an electronic programmable room thermostat that combines time and temperature control in a stylish design that features simple, menu driven programming and a clear, back lit user interface.Among its many new features the C-Stat features an (optional) optimum start function. C-Stat also uses the latest TPI energy saving software for accurate temperature control. TPI is highly accurate and sensitive and can produce savings of as much as 10% annually* on central heating fuel costs. Models in the range feature 24 hour and 7 day programming with up to six temperature settings per day. The intuitive interface ensures they are easy to set up and use. The Optimum Start feature: This (optional) setting will allow the C-Stat to anticipate the next set temperature and switch on the central heating up to 2 hours in advance to ensure the set room temperature has been reached by the time it is due to take effect. Optimum Start
As a consequence the 'switch on' time could take place anywhere between 2 hours and zero minutes before the set time.
21
It is assumed that the heating can increase at a rate of 2°C per hour. Therefore, the maximum extent of this setting is that it can switch on up to 2 hours before the set temperature and raise the temperature by 4°C (with an assumed warm up rate of 2°C per hour).

The optimisation process will be cancelled if any overrides are used during the 2 hour period of operation. Benefits For units without an optimum start or delayed start feature, normal practice is to set the heating to come on approximately 1 hour before it is expected to be up to the set room temperature. For example, if a householder gets up at 6.30am, the heating will typically be set to come on at 5.30am to allow the house to be warm by 6.30am. The benefit of the optimum start feature is that the heating switch on time is calculated based on the temperature sensed 2 hours before the set time. The actual switch on time is then delayed as long as possible whilst still achieving the correct required temperature at the set time. In mild weather conditions, the start time will be delayed until the last possible moment achieving considerable (energy) savings over a fixed 1 hour warm up time. By contrast, in exceptionally cold weather conditions, the heating may be brought on up to 2 hours before the time required but this will not be normal (in the UK) and savings should outweigh the extra heating needed in exceptionally cold conditions. The added benefit of optimum start is that comfort conditions will be improved as the heating will be better controlled and less likely to overheat the house on mild mornings.

Using the Guide First locate the existing programmer or timeswitch in the left hand column of the Programmer Compatibility Guide. Then simply follow the colour coded line over to the far right to find the recommended Horstmann replacement. The colour of the line indicates if it is a direct plug-in replacement or not. Where a 24 hour programmer or timeswitch is recommended, its 7 day equivalent can be used and fitted in the same way. Wiring Comparison Table Before removing any existing programmer it is essential to make a note of wire colours, terminal positions and numbers in relation to the existing backplate. The charts only include programmers or timeswitches where wiring changes are necessary when fitting our recommended replacement. Where a direct plug-in replacement is available or where terminal connections do not change, the appropriate replacement is shown on the Programmer Compatibility Guide. For clarity the Compatibility Guide recommends replacements which are 24 hour programmers/timeswitches. All cases where a 24 hour programmer is stated as the recommended replacement, it’s 7 day equivalent can be used and fitted in the same way.
