The EP line will offer you the possibility to customize your central heating system
and hot water system as desired.
EP110 is recommended for users that want to control only the Central Heating or
the Hot Water system.
EP210 is designed to give you a full control with only one device of both your
Central Heating and Hot Water system.
EP310 is the most versatile product of this line and lets you manage two different
Central Heating zones and the Hot Water with only one controller.

EP310 Controller

The EP310 three channels programmable controller is a stylish wired timer that can be used for two central
heating zones and also for the hot water. Each output will control one zone, meaning that you can create
personalized schedules for each channel.
The EP310 programmable controller will switch ON and OFF your central heating system and/or hot water in
your home as needed. It works by controlling the heating boiler according to a series of programmed settings
that take effect at different times of the day.
By using the EP310 controller you can manage the commands sent to your boiler, motorized valves used in
your system or to your thermostat. You can set the EP310 programmable controller to a 12 or 24 hour format,
the Daylight saving Time (DST) being automatically enabled. The program mode is also selectable between
a 5-2 (Monday-Friday and Saturday-Sunday) or 24 hour format. For each of the programs you can create three
settings per day.
Being a complex programmable controller, the EP310 gives you the possibility to override your programs by
using the Boost function. This can be enabled for up to 9 hours.
For the periods when you are away you can use the Holiday function, which will turn off the relay. The Holiday
Mode can be set for a period of maximum 31 days.
When connected to a system with a non-programmable (digital) thermostat, it can turn the boiler ON or OFF
and control the heating and/or hot water in your system in a programmed manner.
The heating system and the hot water will be controlled with the EP310, meaning that this will send the
command of turning the relay on or off when needed, according to the programs created.
The EP310 programmable controller does not detect or adjust the temperature in your house, it is just sending
the commands to the boiler, motorized valve or the thermostat to turn ON or OFF the relay, depending on the
program settings.
The programs can be set individually for each channel, or, you can program them together if you want your
heating and hot water to be controlled in a coordinated manner.

OFF Mode
Pressing the Mode key 4 times activates the OFF Mode. In OFF mode, the controller gives the boiler the OFF
command, so the heating or the hot water will be turned off.
ADV Mode
Note: In ONCE or AUTO mode, by long pressing the MODE button, the controller will switch automatically
to ADV. You can cancel the ADV by long pressing the MODE key. The device will then return to ONCE or
AUTO mode. You can’t select ADV by pressing Mode key.
When in Auto mode selecting ADV, the controller will simply toggle the current auto setting (ON or OFF).
For example, if the current program is set as:
08:00 ON 09:00 OFF 10:00 ON 11:00 OFF
Selecting ADV between 8:00 and 8:59 will change the output to OFF, from 9:00 onwards back to AUTO (which
is also OFF). Selecting ADV between 9:00 and 09:59 will change the output to ON, from 10:00 onwards back to
AUTO (which is also ON). If the ADV puts the relay ON then the boost would apply immediately at the next OFF
change, if the ADV put the relay OFF then the boost would apply immediately and turn the relay ON.
08:00 OFF 10:00 ON 12:00 OFF 14:00 ON
If ADV occurs at 08:30 and the relay is ON from 08:30 to 12:00. During this period, if at 08:45 +1Hr (Boost) is
pressed, the relay will be ON from 08:30 to 12:00. Boost is applied immediately from 08:45 to 09:45. If ADV
occurred at 10:30 the relay will be ON from 10:00, OFF from 10:30 (ADV) to 14:00 if no +1Hr Override. During
ADV, if at 10:45 +1Hr (Boost) is pressed relay ON again at 10:45 (boost starts), OFF at 11:45 (Boost ends) until
ends at 14:00, then ON again at 14:00.
