Pilot Wire Programming Cassette - Model No. RX9911

T9908/010/A

Display

General Description

The RX9911 can only be used in RPX, EVX and EVS heaters.

They offer either individual programming (each individual heater has a programming cassette) or group programming from a master heater through the pilot wire. Group programming can drive up to 20 slave heaters.

Two heating positions are offered: comfort and economy setback, with temperatures set using the controls on the heater.

A choice of heating programmes are available for each day of the week. There are 7 pre-set programmes, from P1 to P7 or a customised programme P=. The seven pre-set programmes and customised programme will remain stored even if the mains supply is cut off for more than seven hours. However, the day and time will have to be set again as the built in battery will only operate for seven hours maximum when removed from the heater.

Installation

The RX9911 is rated at 230V.

1. Using a narrow bladed screwdriver, carefully release the cover from the slot on the heater
2. Insert the programmer fully so that it clicks into position
3. Turn the control knob on the heater(s) to the PROG position

Individual Programming:

Fit one programmer to each RPX, EVX or EVS heater. (NB. When the heater is installed, the black pilot wire in the mains supply cable should be trimmed back in accordance with the installation instructions.

Programming for a Zone:

The heater containing the RX9911 is the Master heater and connected by the black pilot wire to the Slave heaters. The Master heater determines the Programme and heating levels for all the heaters (Comfort, Setback and Frost Protection), but the actual comfort and setback temperatures should still be set on each individual heater (see heater instructions). The master heater will switch between comfort and setback according to the programme. On every slave heater, turn the position button to PROG.

Electrical Connection Master/Slave Heaters	Do NOT connect the BLACK (PILOT) SIGNAL WIRE to earth.When the programmer drives other heaters, connect the pilot wire from the "master" unit to the pilot wire of a "slave" heater and then from one slave heater to another (in series).Any 240V insulated cable may be used to link pilot wires around the ring main. The signal current is low. Suitable connections would be either an additional single core wire marked or colour coded appropriately or use a 4 core cable throughout the heater ring.
Operating Instructions	The RX9911 can be programmed either inserted directly into the heater or out of the heater. If choosing the latter option, the cassette must be first left in the heater for 15 minutes to charge the battery. Remember that the battery only lasts for seven hours.
