D

Removing actuator

First isolate from electrical mains supply,

disconnect cable from junction box taking note

of position and colour of wires and replace with

new actuator cable (it may be advisable to

replace wire for wire to ensure accuracy), pull

actuator from brass body.

Attaching valve actuator

Engage drive shaft D with actuator E and push

down firmly until spring clips engage fully with

valve body. When all work has been carried out

reconnect electrical supply.

Mid-Position system fault finding

The fault finding table enables quick electrical checksto be carried out on installed Mid-Position systems. Itwill help in commissioning and pinpointing the sourceof any electrical problems.

Only suspect faulty components after you havechecked the wiring and you are satisfied that thewiring is correct.

Fault Finding Identification

ProgrammerCheck links are in place (where relevant).Check mains supply to terminal L.

Suspect programmera. After you have checked that the

switching times are correctly set (referto user manual), and the programmertime is set within a switching period.

b. If live does not appear at JB terminal 8when HW only is selected ON, ONCEor ALL DAY

c. If live does not appear at JB terminal10 when CH only is selected ON,ONCE or ALL DAY.

To carry out the following checks setprogrammer HW and CH to 24h, ON orCONTINUOUS.

RAM1 Cylinder ThermostatCheck wiring against relevant wiringdiagram, disconnect mains supply,remove wire from terminals 2 and 3 andmake safe separately. Re-connect supply.Check mains supply is live to terminal 1.

Suspect RAM1a. If terminal 2 is not live when calling

for heat turn thermostat to maximum.b. If terminal 3 is not live when satisfied

turn thermostat to minimum.

Room ThermostatCheck wiring against relevant wiringdiagram, disconnect mains supply,remove wire from terminal Y1 and makesafe, reconnect supply. Check mainssupply to terminal L.

Suspect RAA21a. If terminal Y1 is not live when calling

for heat turn thermostat to maximum.b. If terminal Y2 is not live when satisfied


CMV3.. Mid-Position ValveSuspect valve if, in any of the followingchecks the valve does not operate asdescribed. Switch programmer to ONposition.

Check A Heating OnlyDisconnect mains supply. DisconnectGrey and White wires from JB terminals 6& 9. Connect Grey and White wires to JBterminal 2.

Reconnect mains supply, valve shouldopen to port A. The boiler and pump willfire and the pipe from port A will getprogressively warmer.

Check B Hot Water OnlyDisconnect mains supply. Valve willreturn to open port B and close port A.Disconnect White wire and make safe i.e.use spare JB terminal 7. Connect boilerand pump wire from JB terminal 5 to JBterminal 2. Switch on mains supply. Theboiler and pump will fire and the pipefrom port B will get progressivelywarmer.

Check C Heating and Hot WaterDisconnect mains supply. Remove Greywire from JB terminal 2 and make safe.Connect White wire to JB terminal 2.Switch on mains supply.

The valve will motor to the mid-positionand stop. Both ports A & B are open. Theboiler and pump will fire and the pipesfrom ports A & B will get progressivelywarmer.

Disconnect mains supply. ReconnectWhite wire to JB terminal 9, Grey wire toJB terminal 6 and the boiler and pumplive to JB terminal 5.

Notes

1. Checks to be conducted by a qualified electrician.

2. Low AC voltage may appear on certain wires or terminals due to back feed from CMV3.. valve. If in doubt switch off supply, disconnect Grey or White

wire as appropriate, switch on supply and check again. Alternatively check with a meter with low voltage capacity.

3. Terminals marked E on RAM must be connected to earth, JB terminal 3.

4. Blue wire on CMV3.. must be connected to JB terminal 4 permanent neutral.

5. For this condition the room thermostat RAA.. must be turned up to call for heat.

6. For this condition the cylinder thermostat RAM1 must be turned up to call for heat.

7. If RAM1 cylinder thermostat is satisfied then terminal 1 on programmer RWB will be live.

8. Please ensure all Earths are connected where applicable.

CZV2.. Zone ValveThis fault finding applies to eitherHeating or Hot Water Zone valves. Checkthat there are no faults on either of thethermostats. Suspect the valve is faultyonly:

1. If the motor fails to run when therelevant thermostat is turned tomaximum. The motor is held in thisposition until the thermostat issatisfied. Turn the thermostatto minimum and the valve will closeunder spring return.

2. If the Orange wire does not becomelive when the actuator is fully opened(the Grey wire should be connected toa permanent live. See note 2).

3. Any auxiliary equipment connected tothe valve i.e. boiler/pump, continues tooperate when the cylinder thermostatand/or room thermostat is satisfied, orthe programmer is in the OFFposition.
