Safety precautions

Installation and connection should only be carried out by a suitably qualiﬁed person in accordance with the current edition of the IET wiring regulations.
E7+ should be mounted approximately 1.5 metres above ﬂoor level, in ‘free space’, away from sources of heat or electrical interference.
Means of disconnection from the supply having at least 3 mm contact separation in both poles must be incorporated in the ﬁxed wiring.
We recommends a separate fused circuit from the consumer unit (24 Hour supply) protected by a 15 amp HRC fuse or, preferably, a 16 amp MCB
Installation of a 100 mA RCD will provide additional protection for the unit.

Connection diagram and cable details
Use a three-core cable with a mInImum conductor size of 1.0mm for a 2kW heater, or 1.5mm for a 3kW heater to connect the unit to the supply.
Connect the incoming wires to the terminal block as follows;
TERMINAL 1 -LIVE in
TERMINAL 2- NEUTRAL in
TERMINAL 3 – NEUTRAL(s) out to immersion heater(s)
TERMINAL 4 – LIVE out to Boost immersion heater
TERMINAL 5- LIVE out to Off-Peak immersion heater
Clamp all surface wiring adjacent to the box or use trunking where appropriate. Secure the heat resistant ﬂexible cords from the immersion heaters using the cable clamp in the box.![SECURE E7 Plus Hot Water Programmer

1. Connection with immersion heater(s)*
  | The 3 core ﬂexible cord should be heat-resistant and rated to 85°C.
  TERMINAL 4 (Boost live output) should be connected to TERMINAL 5 (O-Peak live output) and to the immersion heater.
  The Neutral connection should go to TERMINAL 3 and the Earth connection to the EARTH TERMINALS.
  ---|---
  | The thermostat for the top (short) element is usually set 5-10°C less than the
  thermostat for the long Off-Peak element.
  The 3 core ﬂexible cords should be heat-resistant and rated 85°C.
  TERMINAL 4 (boost live output) should be connected to the short element and TERMINAL 5 (Off-Peak live output) to the long element.
  The Neutral connections should go to TERMINAL 3 and the Earth connection to the EARTH TERMINALS.
  | The thermostat for the top immersion element should be set lower than the
  thermostat for the bottom immersion heater. The 3 core ﬂexible cords should be heat-resistant and rated 85°C.
  TERMINAL 4 (boost live output) should be connected to the top immersion heater and TERMINAL 5 (off-peak live output) to the bottom immersion heater. The two Neutral connections should goto TERMINAL3 and the
  Earth connections to the EARTH TERMINALS.

Note : Refer connection diagram in section 5

Make connections, insert the lugs according to the numbering and tie the wires using the cable tie.
Fix the cover and tighten both the screws
Insert the Wi-Fi module (if required) 802,11 B/G/N, 2.4 GHz wireless router with internet

GMT/BST -Switching time will be changed by one hour. In the GMT/BST mode the clock display will match the actual switching time.
GMT ONLY- Switching will always take place at GMT times (summer and winter). The clock display will tell the correct lime of day.
If Connection is to be made where a 2-Rate electricity meter is controlled by a Radio Teleswitch or other equipment which control tariffs remotely or seasonally, it is essential that before setting the commissioning switch you ﬁnd out how the off-peak times are controlled.
The Customer Service Centre of your Electricity Supplier will conﬁrm information regarding Off-Peak electricity timing and the switching method used for your area.
On installations where the 2-Rate electricity meter is controlled by a mechanical Tariff Time switch the commissioning switch should be setto GMT ONLY.
Home screens Notes: 1. One of the above screens will appear on power up 2. appears only when E7 +is connected to the Wi-Fi network.
