Danfoss Randall FP715SI Heating Programmer

Product Information

The soap dispenser arrived on the date stated but was slightly defective. I phoned the local supplier and it was replaced the following working day. Excellent service. Additional features such as service interval timer, convenient user overrides, built-in ready-to-use programmes, a day programme copy facility as well as a stylish, compact design and easy to read display make the FP715 Si the simple answer to all heating and hot water requirements. However you say "Turned the thermostat right down but heating stayed on." which does not seem to point to the programmer.

My advice: Find an electrician who enjoys heating controls and let him/her select the product that will do the job. Otherwise you’ll buy the wrong thing and waste your money. Although your likely not considering swapping all TRV heads to linked heads now, before selecting a replacement you need to consider what you may want to do in the future. Thanks for your considered responses. I have the manual but when I follow the instructions to reset the date and time, it just doesn't work! So, I have just come to the conclusion that updating it makes sense.The FP715 Si two-channel full programmer has separate heating and hot water outputs operating on completely independent time bases for maximum flexibility. I was hoping to be able to do this myself, as I like to learn new skills, but it sounds like this would be a step outside my comfort zone

It seems the Drayton Wiser TRV head is about the best, with algorithms to work out how long it takes to heat a room without over shooting, and the base has the option to work with OpenTherm with an add on module. Since I use oil OpenTherm does not interest me.In terms of installation, the FP715Si offers flexibility. It can be hardwired or configured for battery operation, depending on the user's preferences and needs. This ensures compatibility with a wide range of heating systems. Furthermore, the FP715Si is equipped with temperature compensation technology. This means that it can automatically adapt to changes in room temperature, ensuring consistent and comfortable heating throughout the day. The Danfoss FP715Si is a thermostat that offers precise temperature control for residential heating systems. Designed with functionality in mind, this thermostat allows users to easily adjust and maintain their desired indoor temperature. An additional range of accessories allow the FP715 Si to be used in other upgrade situations where the unit being replaced is larger than the new unit and a decoration scar would normally have been left. Probably it would need connecting to the wiring centre, not to the controller as you have with the TP9000.

The FP715 Si two-channel full programmer has separate Heating and Hot Water outputs operating on completely independent time bases for maximum flexibility. I apologise that this has turned into a bit of an essay, but any expert help you could pass on to me would be greatly appreciated. But can I bypass the wiring of the danfoss to just make the CH on all the time, so it can then be left switched off on the danfoss? Or does that confuse it?! It seems to have been doing it more often recently so I figured I'd try moving it out of the airing cupboard incase it was the heat affecting it. I drilled a hole in the wall and mounted it in more or less the same place on the other side (so now in the landing). So, from what I am gathering, I can buy pretty much buy any 2-channel CH/HW controller, but need to get a good sparky in to do the necessary wiring and installation. Can I confirm if you all agree that this is correct and a sensible approach?If however as likely it switches 230 volt, then you can fit a system which can link to TRV's in the future allowing you to control each room independently. Discovered during the night that the central heating was still on despite the programmer indicator light being off. Turned the thermostat right down but heating stayed on. Time for a new programmer. But the Hive is much simpler and cheaper, no option for Opentherm, and no cleaver algorithms, and the base stops taking a demand for heat after 22ºC so the base unit really designed to be in a room normally kept cool, like the hall. I guess I will just plump for the 2 channel controller that I like best and hire a sparky to install it (I know my limitations). At the point of installation, you can choose to have either a 7-day, 24 hour, or 5 day/2-day operation. You can then set 2 or 3 on/off points for each day, enabling you to make your central heating work to your schedule. Additionally, the programmer can be set for either ‘pumped’ or ‘gravity’ hot water.

As it works with just one thing on at once in my case, is it possible to bridge the wires for the Central Heating so that it is in effect on all the time but could be left in the off position? So I'm not sure if the programmer is just duff, or if there is a certain combination of events which is causing the programmer to trip out. Earth, neutral and live is fairly self-explanatory. Am I correct in thinking that the following applies?One of the key features of the FP715Si is its multiple switching options. This thermostat can control both the heating and hot water systems, providing convenience and flexibility. This allows users to manage their overall energy consumption effectively. Relieved to see that this programmer is still available but thanks to coronavirus getting a tradesman to fit one could be a problem as we are in isolation due to age. The FP715 Si can be configured by the installer at time of installation to provide 7 day, 24 hour, or 5 day/2 day operation and to provide either 2 ON/OFF"s or 3 ON/OFF"s per day, allowing the time control to be tailored to match the specific requirement of the consumer.
