TP-87 programmable digital-bus thermostat 1 / 2 MKL52201
The TP-87 programmable digital-bus thermostat
The TP-87 is an indoor thermostat with a programmable weekly heating
schedule. It is designed to work exclusively in combination with
AC-8007 / AC-8014 devices. The thermostat provides indoor temperature
regulation which balances economy with comfort. The device is capable of
recognizing warm-up persistence characteristics (within 2 days) and will
adjust the settings accordingly so that a high level of operational comfort is
achieved. You need not find out how early the heating should start in order to
get to a comfortable temperature at the desired time. The required timing is
Temperature adjustment can be performed by simply turning the setting
The following features are also available:
• Anti-freeze protection – any drop in temperature under the
(configurable) AL Lo value is detected and signalled to the receiver,
causing the receiver’s FRE output terminal to be activated.
• Floor temperature detection – the thermostat is equipped with an input
terminal for temperature sensor connection. This is especially suitable for
under-floor heating control – by placing the sensor directly into the floor
the heating regulation can be performed with higher precision.
When combined with an Oasis wireless security system (Jablotron), the
following are possible:
• Switching the heating ON and OFF remotely (by mobile phone, remote
control or Internet).
• Disabling the heating when windows are open.
• Informing the user about heating faults.
• Informing on the occurrence of fire (when the temperature is above a pre-
The TP-87 should be mounted in a dry indoor location. Choose a mounting
