AC-8014/814 receiver 1 / 2 MJQ51505

The AC-8014/814 receiver

The AC-8014 is a 14-channel receiver of signals from TP-8x wireless

thermostats working on a frequency of 868 MHz. It can also be used

with TP-8x digital bus thermostats. The AC-8014 can efficiently control

multi-zone heating (including thermoelectric actuating valve-drivers to

replace thermostats on radiators) or cooling systems. The receiver has

a special MODE channel which turns the heating to economy mode. It is

designed for heating system control and is not suitable for extending

hardwired alarm systems via wireless detectors.

Due to the maximum current limits of the outputs, pulses switching the

outputs off for short moments are used (when more then 8 outputs are

used). Therefore the AC-8014 should only be used with thermoelectric

actuating valve-drivers. It should not be used to control any relays,

semiconductor switches etc. LEDs on the receiver’s front cover indicate

the status of each output channel.

The AC-8014 can be considered a hybrid of two components: the

AC-814 digital bus receiver and the wireless module. The AC-814 only

allows connection by digital bus and can be supplied standalone as a

cut-down variant of the AC-8014.

The AC-8000R built-in power relay module can be used as a pump

control. A second AC-8000R module can be plugged-in to provide boiler

control. Both relays work with OR logic: they are switched if any of the

1–14 outputs is activated.

Installation

Attach the unit to the desired location with three screws. Route all the

cables to the unit before you tighten the case.

Fix the cables firmly inside the box by a sliding strap.

Note: Only a qualified technician should provide installation and

servicing. The user is not allowed to open the cover and/or make

any modifications. The mains cable must also be fixed outside the

receiver’s case. Replace the mains plug if necessary for your

country.

Terminal description:

AC, AC – power input 24 V AC.

SUM (summer) – input terminal. When switched to ground, economy

mode is activated. This is indicated by the MODE

channel LED lighting.

FRE (freeze) – output terminal. If any of the thermostats sends a

signal about the temperature being under the value

of the ALLo (critically low temperature) parameter in

the thermostat, this terminal switches to ground for

10 seconds. The terminal’s maximum load is

100mA.

BUS,BUS – terminals for the digital bus connection (for

thermostats of the relevant type). Maximum length

of the connection cable is 200m.

1–14 – channel outputs, switchable to ground. The

AC-8014 has pulsed switching.

COM – common positive output terminals 24V DC.

Terminals of the AC-8000R power module:

L_A, N_A, PE_A – power supply input for the circulatory pump or

boiler (use an external fuse for its protection).

L_B, N_B, PE_B – terminals for the circulatory pump or boiler

connection (the L_B terminal is triggered if any of

the 1–14 outputs are switched on).

The receiver is protected against shorts on the output. If the output is

overloaded (the current is greater than 0.4A), then the output is

automatically disconnected. A fault is indicated by rapid red flashing

of the corresponding LED indicator. The output is under constant

monitoring and when the output current decreases below 0.4A the

output will be switched on again.

If it is necessary to have more channels, then it is possible to

connect another unit via a 4-wire cable connected to terminals 1–4. In

this case a single wireless unit should be shared by both receivers.

However, each receiver only controls its own built-in AC-8000R

module.

There is an available connector for an external antenna (e.g. AN-80

or AN-81) on the bottom side of the front housing. If the external

antenna is used no further modifications to settings or connections

are necessary.
