The Center EHE0200361 is an easy to use and high-quality modern wireless thermostat that’s ideal for use in a wide variety of heating installations. A popular part of Plumb Center’s huge range of wireless heating controls, this product includes a large LCD display with backlighting to assist customers during daily use, as well as an array of other useful features including a 24-hr clock display. This room thermostat communicates with the relay box on an 868MHz Radio Frequency (RF) band to control a single central heating system component such as a boiler, pump, or zone valve. Neither product will communicate with other RF products that use different frequencies or communication protocols.
A programmable thermostat is a combined timer and thermostat in one device. This means that when programming, in addition to setting the times you want the heating ON, you have to set a temperature for each time period too.
Important note: A programmable thermostat will never completely switch off as all ‘off times’ require a setback temperature, if the temperature in your home drops below this point, the thermostat will operate the boiler until the room reaches the set back temperature.
If setting the programmable thermostat to switch on and switch off, you have to set what temperatures you require
The key difference to a room thermostat and time clock system is that you can match different temperature requirements to specific time periods. This allows you to raise and lower the temperature automatically at specific times to suit your lifestyle.
The programmable thermostat is NOT designed to be an ON/OFF device. Unlike a heating time control, your programmable thermostat is always working 24 hours a day to ensure that your property is heated to the temperatures you require.
So remember, it is important that during the periods that you only require protection from low temperatures i.e when you are asleep or out during the day, that you set the time period to a low temperature.
For example, if you do not want your heating to operate during the night or during the day when no one is at home, we recommend that you set the temperature to 5°C during the appropriate time period 2 and 4 shown in the table below.
Some of the most frequently asked questions we receive are due to a misunderstanding as to how the thermostat operates – questions such as:
‘My programmer is not turning my heating off and my heating comes on in the middle of the night or day when I don’t want it to’.
These questions are easily answered:
If your heating operates at times when you believe it shouldn’t, check that the temperature you have set against the time periods where you don’t require heating is low enough to provide frost protection (5°C)* but not high enough to instruct the boiler to operate in normal temperatures.
Below is an example of how to set the programmable thermostat if you want to the heating to be OFF at periods 2 and 4.
ON time and temperature - Start of the day
OFF time and temperature - Usually set for when the person leaves for work
ON time and temperature - Usually set for when the first person arrives home
OFF time and temperature - Night time; no normal heating required; property is protected against low temperatures
