2.6.1 Charge Control
The charge control registers the outside temperature and converts this value into a control current. This
current is passed via the control wires A1/Z1 and A2/Z2 to the control resistance in each storage heater.
At the same time, the temperature in the heater core is also registered. The switch-off point of the
charge thermostat is therefore determined by both the outside temperature and the temperature of
the heater core.
In this way, a control of charge according to the outside temperature and the residual heat in the heater
is achieved, thus complying with Energy Saving Legislation.
The control wires can be run together with cable feeds L, N and PE.
Please also read the Instruction Leaflet supplied with the Charge Control.
2.6.2 Room Thermostat
The discharge of the storage heaters and thus the regulation of the room temperature is achieved using
a room thermostat.
The type of thermostat and its configuration is dependent on the heater installation and the
requirements of the user.
Please also read the Instruction Leaflet supplied with the Room Thermostat.
Integral Room Thermostat
The integral thermostat is designed for direct mounting to the heater itself:
●
Thermo-mechanical room thermostat:
This type of thermostat switches the heater fan ON or OFF, according to the temperature
required.
●
Electronic room thermostat:
The speed of the fan is regulated electronically according to the required room temperature.
External Room Thermostat
Following thermostats can be supplied:
●
2-point room thermostat
●
2-point room thermostat with thermal feedback
●
Electronic room thermostat
2.6.3 Thermal Switching Relay
By installing a thermal switching relay into each storage heater, the Utility relays in the junction box
can be omitted.
Make certain that the installation of a thermal relay does not violate installation Codes of Practice of
your local Utility.
Please also read the Instruction Leaflet supplied with the Thermal Switching Relay.
2.6.4 Day-acting Element
Using the day-acting element the heater can give off warmth immediately even if it is not charged at
all. The day-acting element works on the ON-PEAK Tariff.
Switching and control of the Day-acting Element is to be carried out using an integral or external room
thermostat suitable for this purpose.
Please also read the Instruction Leaflet supplied with the Day-acting Element.
