Setup
The TPOne-S can be used as a single channel
programmable thermostat to control the
temperature regulation of the heating system only
or as a two channel programmable thermostat
to control the heating and the time schedule of
a domestic hot water circuit. The domestic hot
water selection will have been chosen in the
startup wizard on initial installation. Choose this
setting after installation to switch the domestic
hot water option on/off.
Default: Set at startup
Note: Settings in the menu which are required for
domestic hot water are only accessable if the Hot
Water Setup is switched on. TPOne-S controls
only the time schedule for domestic hot water and 
should always be used with a suitable hot water 
cylinder thermostat.
RF Pairing The TPOne-S must be paired to a compatible 
receiver/boiler relay.  The initial pairing is made 
in the startup wizard.  If pairing was not made at 
startup or if pairing is required to a new receiver/
boiler relay select this setting to start new pairing.
Control Type This allows the thermostat to be set to run in On/
Off mode or in chrono-proportional 3, 6 or 12 
cycle rate.
Default:  Chrono 6
Note: for condensing boiler control tests have 
shown that boiler efficiency is significantly 
improved when controlled by a chrono-
proportional type controller
