MK18 Range - Electronic Time Control Range
with Service Interval
Features
The MK18 range has all the fl exibility and reliability
of its predecessor but with a more elegant look
and some handy new features. The addition of a
real time clock means that setting the time and
manually adjusting for summer winter time changes
is a thing of the past.
All units in the MK18 range are set to operate
straight from the box with default settings, but the
inclusion of a full range of customisable user and
installer settings provide ultimate fl exibility when
setting up the unit.
The MK18 range consists of 3 products:
TS715 Si / TS715Si-CB Electronic Timeswitch - A
single channel unit, with voltage free switching
contacts. Ideal for combi-boiler installations and
anywhere you require low voltage switching.
CP715 Si Common Timebase Programmer - A
two channel programmer providing heating and
hot water outputs. Each output can operate
independently of the other, with common timing
for both channels.
FP715 Si Full Programmer - A two channel
programmer providing heating and hot water
outputs. Each output can operate independently of
the other, with separate timing for each channel.
All three models use an industry standard 6
pin backplate making the MK18 range an ideal
replacement for many existing products.
