This small accessory is designed to convert our Heated Bat Boxes into programmable heated bat boxes.  It is easily installed in a few minutes and then the dates for switching the heater on or off can be set.  Once set, the heater will come on and off on the same set dates every year.

Installation of the plug and play Yearly Programmer is easy, doesn't require any tools or particular expertise, and only takes a few moments. It is first connected to the Heated Bat Box (it goes inside the building next to the temperature controller in the cable going to the bat box, and simply uses the existing connectors).  The current time and date then needs to be set, and the dates set for switching on and off.

The device will then switch the bat box heater on and off on the same dates every year.

The Yearly Programmer draws power for switching from the temperature controller, and it retains the time and date settings using a small internal battery.  This means it does not require a separate power supply and it avoids needing additional cables.  It does not need an electrician to install it.  The bat box's temperature controller continues to regulate the temperature inside the bat box, and the protection against electric shock provided by the RCD plug (which is part of the Heated Bat Box) also covers the Yearly Programmer.

This accessory extends the functions of the Heated Bat Box to become a programmable heated bat box, and can be fitted to new Heated Bat Boxes, or retro-fitted to boxes already installed*.  It is designed to match the simple good looks of the temperature controller and is exactly the same size as the temperature controller.   It can be positioned side by side with the temperature controller, or stacked on top to save space.

The Yearly Programmer has the capability to allow up to 16 separate heating periods per year.  Most applications however will only require the use of one heating period - A typical setting will be for the heater to switch on in Spring (eg 15 April), and off in Autumn (eg 1 November). 

* The standard Yearly Programmer has blue/black connectors which match the connectors on current Heated Bat Boxes and those produced in the last few years.  Some earlier bat box models used different black connectors on the cable to the bat box.  If you wish to connect the Yearly Programmer to one of the older Heated Bat Boxes with the black connectors, please let us know, so that we can fit alternative connectors to your Yearly Controller.
